Advice on what to do please

How do you learn about mistakes?

By making them, that's what adults do, they fk up, think.."hmm, that was shyt..let's not do that again."

Ta da...welcome to the learning curve.
It's shyt, it's hard, it hurts, but that, hun, is just life.
Welcome to adulthood.

That's nice but this is not about "doing laundry". I have a blockage with people to the point that things between us get into a huge conflict and they distance from me even though I try hard to fix it. People just get distanced from me whatever I am doing it seems. It is just weird going into the kitchen to cook and being silent or saying things which get no response.
I do the practical things myself, that's not the point. I do "give back" as far as I know. Mostly though my relationships don't get to any deep level.
And obviously making mistakes has not been fruitful, it just makes it worse because I don't often see what is wrong..
Why just make sweeping assumptions?

Have you tried reading self help relationship books?

The simplest thing I learned in kindergarten is so true: "Do unto others as you would have others do unto you". That's really all there is to it. And "do" is an action.

When you throw a child into a pool, they will just start swimming (which I don't advise doing literally).

Get out of your parents' house as much as possible. They are strange with this silent treatment and neglect. That's THEIR problem. Find others to fulfill and teach you. Find better role models. Maybe a job where you have a good boss who can mentor you.

For some help, look into the ONLINE DBT Interpersonal Effectiveness section. If you cant get into some DBT therapy where there is guidance & teaching of those skills. I dont know if you are capable of learning without being taught by someone (my ex H had to be taught everything). But at least it provides some groundwork to grow from....BUT YOU HAVE TO DO THE WORK & change yourself & without someone holding you accountable like a T its a lot more difficult.

You have to TAKE RESPONSIBILITY for your own behavior.

I learned from my mistakes even though I didnt SEE what was wrong I FELT it....& tried to think through how NOT to experience that uncomfortable feelung by running numerous different scenarious through my mind so that the next time something happened I couldbtey a different approach. I didnt learn except by observing what I didnt want to be like griwing up because as Erebros said, people with ASD think differently & I grew up with a dad who was that way so I had to sort out my interfaces with people ON MY OWN. Starting long before kindergarten.

Some people ars capable of learning by observation, not having to have their hand held every step of the way....I lived with a H for 33 years who was like that with everything that required common sense. Honestly its exhausting to be around people like that.

Have you been Dx'ed by a T for any REAL mental issue that is causing you to be this way. ASD is known for having communication & personal connection problems as one of the behavioral traits. Might be worth looking into so you know REALLY what you are working with. Sometimes even just being barely on the ASD spectrum & difficult to DX can be cause for the problems you are having. Best to know & eliminate that not know why you ate having so much struggle & the blame cant just be put on parents because many of us with incapable parents still learned how to communicate better than them
