I hate my family... Please help..

--------------------------- PLEASE READ ----------------------------------------%u 2026

I'm 15 years old and I hate my "family". I hate myself. I hate my life. I'm seriously considering overdosing on pain killers so I can die. First, let's start with my "dad". I cringe when I call him a "dad". He's doesn't do ANYTHING all he does is sit on the couch all day long watching tv. And when he actually does go to work, he comes home and does the same thing. He doesn't help my "mom" pay the bills for anything, he treats me like **** by calling stupid, etc, and he yells EVERY SINGLE DAY. Him and my "mom" are always arguing and yelling. Now to my "mom". She obviously wants me to graduate and leave so she can move on with her life. She told me that exact statement just a few minutes ago. And, I could tell for the past years that she never liked me. I was ALWAYS the first person she blamed for every thing that happened. Spilled milk, me (even though it was my "sister"), cracked glass, me. Everything is my fault. And, whenever she looks at me I notice her giving me a really cold look. I catch it at the corner of my eye. And it hurts me so much inside because I used to love my "mom" to pieces when I was younger. Matter of fact, I used to love my WHOLE "family" when I was younger. Things change I guess..
Now to my sisters.. my middle "sister" is turning 13 tomorrow, and I'm not going to wish her a happy birthday or anything. She is so FAKE. One day, she's acting all nice with me. Then, one day she turns her back on me and hates me. And, she always calls me dark. I'm caramel-skinned and she calls me dark, just because she's lighter than me. Now, I've been bleaching my skin for a year and a half now. I've gotten so self conscious because of her, she make fun of every part of my body. My curly toes, my small gap in my teeth, skin color, etc. It's unbearable and the fact that society likes lighter skinned girls better makes me even more self concious and want to kill myself. And my youngest "sister".... ugh, we got into a fight today at the dinner table not too long ago. She called me a *****(and she's 11..) and threw food at me. So, I threw my teacup at her. I was sick and tired of her. I NEVER had a relationship with her, maybe when I was 4 or 5 but when I got older I hated her so much..
And, I've been so stressed. I haven't been doing good in school this year, my family is is making me build all this anger inside, and.... ugh it's just so much.

You just do NOT understand how much I hate everything right now. My family, my life, my skin color, everything.
