I really need someone to listen

Hello there! If you entered here it means you might know how i'm feeling and maybe can help me.
I'm 16 years old and live in Costa Rica, and i'm not sure whether life is worth it anymore. I know it's dumb since i'm young and have my whole life ahead of me but i still can't help but hope i simply disappear.
I'm not saying i have a full blown depression or anything, but i certainly feel depressed.
The worst part is that i don't really have anyone to talk to... I do have friends and family but most of my friends aren't really that close and i can't talk to them about it because then they'd say things like "oh, you just want attention" or "stop being so dramatic". And i also tried to tell my parent's but that didn't go that well. See, my mom suffers from depression so me and my sister usually have to pretend like everything is okay so that she'll feel happy. But this one time i got the guts to tell her that i felt like i didn't want to live anymore and like life's just a horrible thing that i no longer want to go through. The sad thing was, instead of doing anything about it she just went into her room while i cried telling her and locked herself in. So me and my sister kept knocking on her door for about 3 hours and when we looked inside the window there she was, laying on the bed simply sitting there, doing nothing. Then my dad came home and the **** hit the fan.
Well here's the thing about my dad, he's not the most loving guy in the world. He's usually very cold and barely says "I love you". And that sucks. He has only said "I'm sorry" about 8 times in my life (seriously, i've counted them) and he's the type of guy who would rather give me money to go watch a movie than spend some time playing a board game with me or something. I don't know why i'm telling you this but still, at least now you know.
So he comes home and i'm just sitting in the couch, my eyes red and sore from crying, and he asks where mom is. I tell him she locked herself in and that she won't come out and right then he responds "what did you do now?". Not gonna lie, that kind of hurts you know, to be blamed right away instead of asking what happened. So i tell him that i said i wanted to kill myself and she went to her room and he simply looked at me and went to the room. What a great father! After about fifteen minutes he comes back and says he wants to talk to me, so naturally i agree (i was actually happy because i thought that maybe he could help me out or something). But since my life isn't a wonderful one, he said that i was being a selfish, stupid, idiot and that i just wanted to manipulate them to get attention. **** ME. I had been considering it for months now and the one time i decide to tell them that is what happens. Also, he really likes to insult me and my sister (usually with the typical "stupid" or "idiot" but sometimes he gets creative. And he is also a fan of using the belt as a punishment (quite the cliche if you ask me, the angry latino father hitting his children in the *** with a belt while they cry and beg mom for help or at least mercy.
So yeah, that's pretty much it for now. I'm too much of a coward to do it because i'm not a fan of pain and don't really know how to do it. And i try to have some sort of hope for the good things that could come (the main one is the fact that i want to study mechatronical engineering and it excites me), but it's kind of hard since it's still far away and all that.
I know i sound like an ungrateful a-hole because i have a roof over my head and food and can actually have the luxury of studying in a good school and, eventually, going to college, but i'm not really that much of a *****.
I try to distract myself a lot, i love reading (The Catcher in the Rye is my favorite novel but i also enjoy reading about science and math), and i listen to a lot of music. Yet still i feel like it would be easier to simply kill myself and free the world of a burden, no matter how tiny and useless.
I really hope someone replies.
Ps: I'm very sorry for my crappy English, but at least i have the excuse that it isn't my first language.

Hey Pink,

Thank you for sharing! And I am so sorry that you are going through all of this. Just know that you are not alone.

Also know that it WILL get better! Once you are out on your own, things will change. It still may be stressful at times, but things will be okay!
By the time I was 13, I tried to end it. But I am so glad that I didn't. I am now 28 and live a pretty nice life. Sure I battle with depression, but I am strong because of what I went through as a child (I also had an abusive father), and I know now that I can make it through anything. Just give it time, girly!

Dear Pink, I can relate to your feelings of helplessness/hopelessness. I was raised in a similar way. My mother was very anxious and depressed and we were also often beaten for upsetting her. At 16 I tried taking my own life i regretted what i did and told my older sister. She called the doctor to see how to help me but I was never taken to a doctor or psychologist for my depression. I grew up learning to keep secrets and pain concealed. This is not a good feeling. Luckily I hung in there and went to University. I have a great career, married,children and I am still enjoying life. I still suffer with depression but I am not ashamed of it and know when to get and give help. My daughter was diagnosed with depression at 16. I was able to give her the support I never received and she also is in University and enjoying life. What I'm trying to say is I am sorry for your current situation. You seem bright and intelligent and have something to look forward to in the way of goals. What worked for me is surrounding myself with positive people and friends. When I went to university my life changed for the better. Always remember that although things seem bleak now it is bound to get better. Try to be close to your sister and help each other. My younger sister was my confidant. I wish you much happiness and success in your future. In my country you do not need parental consent to see a psychologist or therapist. Never be ashamed of how you feel and keep asking for the support you deserve!

Hi Pink, I'm so sorry you have so much going on at the moment and life is so hard. Please listen to the other posts, it is possible for things to get better. Remember you are a human being and therefore as good and valuable as anyone else. Anyone who tells you different is, in my opinion wrong. So hang on to life as best as you can. Time WILL pass and you will be able to leave home and make your own life. I really, truly hope you can.

Ps, your english is excellent!
