I want to know,if I go to social services and request it, and explain the situation I'm about to explain, will I be able to go into foster care?

Have you ever felt like you're in a restricted area, and everyone's pushing you out? I get that every day in my house. Every day, if I even talk to someone for a second, I get the strongest feeling of "You don't belong"
I try to cover it up, make a few jokes, but I can't shake it. It's haunting me.

I don't go out much, I spent most of my life playing video games so I never went outside much. It was an escape, why focus on my problems when the princess is in another castle?!
Now my dad's gone a bit mental over it. He refuses to just let me stay in my room, insists I go outside. He even went so far as to take away my TV and computer. All because I like it inside.
I know other people have it worse than me but I just can't stand another minute in this house.
My mother's a drunk who wishes I was someone else, someone more like her, a gossip who spends all her time fixing her hair and talking on the phone. I'm not that girl. She tends to blame me for everything, it's like she's constantly mad at me for not being that girl.
My brother is 7 years older than me, and it just seems like he doesn't like me. He's always hitting me or arguing with me or telling me to leave. He's 23, shouldn't he have stopped with the moody teenager act? Not only that, but in an argument, he can punch, yell at and kick me,my parents won't say anything, however if I try to defend myself, without violence, I get more yelling. It's like I'm constantly having to defend in my own home.

To top it all off, not once have any of them taken an interest in me. I spend all day at the computer because my best friend, the only person I've ever felt connected to, lives in another country. She moved to the UK two years ago.The only way I can talk to her is through the internet.
What need have I go to outside when there's no one to hang out with? I have no friends living near me and even then, I'd probably be miserable and angry that I was forced out.

I feel like every time I walk outside my room, i make the whole house uncomfortable and I want to end it. I've considered running away, and after a particularly bad fight I was considering suicide. I locked myself in a room, shut the curtains and just cried for hours.

I don't want to go back to that feeling again, and I feel like if I don't leave, something awful will happen, and it scares me. Even thinking about it now I start crying.

So that's it. Now I need the answer. Do I have grounds for foster care? And if you think I do, can someone give me the information?

Thank you for reading this.
