Advice on what to do please

I really don't think that will help...

I'm starting to think we've been had and these demands to be taken care of like some 4 year old is actually the work of ye who lives under the bridge.

Its just too far out and makes absolutely ZERO sense!

Why do you think that?
That's the truth ... it is that I've been set up for failure from the start purposefully.
What is far out?

Daily Routine:
Get out of bed. Get dressed. Eat breakfast. Apply for jobs or go to your job. Work. Eat lunch. More work. Go home or go out after work. Relax and watch some TV or internet. Go to sleep. Repeat.

Weekends: linger in bed, eat, clean your house, shop for groceries, do chores, visit friends, go to religious services, have a hobby , have a date, Repeat.

You are an adult. Demands for other people to take care of you as you are a little child are unrealistic.

Then apply for a job.

Excuses ... all your " I cant's " are excuses to stay in your stagnant life, a life you are choosing,
a life you feel that people must stop there life and take care of you.

You have nothing to lose by trying anything to get at least a shot at finding happiness.

Do you mind if I ask you you're age ?

Something just doesn't make sense if you are not a very young person.

I agree you need to be on a psych hospital if you really are the way you present to us ...

I tried.. it really does not help what I do. I am struggling with similar alienation and I end up alone.
I am toward my mid-twenties.
I am not choosing a life like this, I feel trapped and don't know what to do to bring significant change.

Make small goals that you can meet, you can apply to one job a day < goal

Why does it sound like I am not being serious?

Are you out daily filling out applications?

Maybe you are and I missed it ??

I have tried applying for jobs. Right now I don't know how long I will stay here and nobody wants to take me for less than months.
That doesn't really help my trouble with people where I still don't know where I'm going wrong. Most people will not say what you're doing wrong.

We don't know for sure what you are doing wrong but few things come to mind

You sit home all day, it's not conducive for making friends. People wouldn't want to connect to adults who sit home all day.

You blame others and expect others to fix your life, it might be off putting in real life. Adults take care of themselves.

You ask questions, but ignore answers or argue, you maybe don't understand what people are saying, otherwise why do you ask, that's typically unpleasant for others.

You contradict yourself. It's off putting in real life

You ask, so these are things I am observing

Ok. It's an opinion. But I don't just blame everyone, there is just two people I am talking about.
I feel like I am rotting away. It is sad that this is happening. I wish somebody cared and I hope someone will care... I don't know.

We care but we can't fix it. It's anonymous forum. Your parents didn't do a good job but since you are a grown personYou can't demand anything. You can demand but they aren't going to do it. You can't make them. So you need to do something different.

Ok. Where can I learn to live like a regular person? I am very worried about myself like this. I have now been inside alone almost two weeks excluding going to the shop twice...
You can't demand anything? I can't rot in obscurity, that is what I really can't do. If at least he does not do something, and he didn't, then I really don't know. It doesn't look like a good quality of life. As I said what if I end up a broke older woman at grandma's? Not to mention where is my own life. Don't think anybody would say a word so everything points to the fact nobody cares. At all. I don't know if I will learn anything at grandma's or nothing. And anyway parents are supposed to take care of you or I would have been better off in an orphanage. I am in a very bad situation.

You asked where you can learn life skills. Talk to your therapist and psychiatrist. If you don't have a therapist see if you can find one. Or disability mental health services in your area or vocational rehab services. Tell me where You live and I'll try to find you local services.

Yes parents are supposed to take care of children. Not adults though. You are grown. You can't go back and be a child.

I have tried that here (therapist) and it has actually not been helpful. All I got was a chit-chat, so I feel less alone that one hour a week. It's expensive and not worth it.. They can't teach you life skills, they don't even know what your day looks like.
Doesn't matter, I can't live like this. I don't care if I am 100 years old. I can't stay isolated. If I do it doesn't matter whether I work, or even exist. I don't need to go back, I have needs now. I need others' help past 18, so WHAT? Sometimes you need even more help once you are past 18. Do you think that is some magic number?
If I can't keep going, then I can't keep going. Others can ignore it all they wish. It will probably get worse. Just because I can talk about it on a forum does not mean I am not at rock bottom. I have not been treated normally and cannot live like this anymore and can't help myself very much, so someone else must.
I have nowhere else to go than to grandma's just now.. I don't know.
The way she treats me is horrible. There is ZERO responsibility or real care. If you read what she writes to me, you might think she is joking. And she left me lonely all my life, she hardly spoke to me in the house. So I am just to rot, just because someone wasn't bothered? No.

First things first. Move out of your current living situation. Go to your grandma's place. It won't be perfect, but you won't be alone like you are now. When you get there, go to the library. Find some books on psychology, development, biographies of people you admire, whatever you need. Make it a research project. Learning from other people's experience is a start. Then join your local church. Go to services and see if there are any social events you are interested in. If you can't get access to a doctor for medication, find a place that sells herbal things like St John's wort. That will help to begin with. Then see if you can find a bicycle. Make yourself go out for a ride every other day. See if you can write a timetable for yourself like at school. Mondays library, Tuesdays bike ride (and so on). Each week will be better than the last week. Think of it like you are climbing a very long flight of stairs. Your family did not give you a map, but there are other ways to climb up. And as you climb, you will slowly feel better and do better, and your relationships with your friends and family will improve. You are trying to do too much at once, which is why you feel overwhelmed and unable to cope. So one step at a time. Leave your apartment. Next step, go to grandma. Next step, get a library card. Next step, find the local church. Keep going, and keep posting! You may feel people on here don't understand you, but I think we come from similar cultures (Eastern Europe). It will get better!

Basically you are saying once you hit 18, it is too late for anyone to help? I don't believe that and never will..
I was supposed to continue with education this year. But like I said I need to find help while I am young, I fear going there alone for the several years might not affect me well. What do you think?
Also since this is happening, can you please tell me WHERE to turn for help with my life? I explained about psychiatrists and therapists already. I need something more concrete. Do you know of anything please?

More concrete? I think talking to a doctor or therapist is very concrete. But ok. Mental health services in your country. Disability office. Vocational rehab. I don't know what your area offers unless you tell me where you live.

Yes family might help each other at any age. But not everyone does. You asked them to help and they do not. So you accept that they won't help and look for other resources. It's unrealistic to sit and wait for family to help you if they clearly aren't doing it.

"learned help·less·ness"
ˌlərnd ˈhelplisnəs/
nounPSYCHIATRY
a condition in which a person suffers from a sense of powerlessness, arising from a traumatic event or persistent failure to succeed. It is thought to be one of the underlying causes of depression.

You are a very intelligent, well-written person. Time has passed for your parents to teach you life skills. Only you can pick yourself up and learn to live. Just do it. Sending you strength.

I have another question. WHO can help you discover what you are doing wrong with people and why you have difficulties with relationships? Generic stupid advice like "find new friends" is not helpful. And I haven't found therapists doing this.

Seems you have been to the wrong therapist and trying the wrong type of therapy.

Explain to me why my 10 year old autistic son can get out of bed, get himself dressed for school feed himself breakfast, get his bike and ride a Mile to school all without requesting any help. But you can't?
He has no friends, no peers that understand him. Even as his family we struggle to understand often, as he sees things very differently from us.
Yet he does it, every week day without fail.
On the weekends he plays with his dog and does his own laundry.
He is 10.....10!! And Autistic!

Crawl out from under the bridge, and join the military. If you need your life organised for you.

Also no one will befriend or socialise with someone who just takes and takes. At some point you need to give something back or you are going to be very very alone.
