Help me get me to the UK and away from my mom's boyfriend

I'm from Texas and recently I've found myself stressing more and more nearly reaching mental breakdowns again and again due to the state of the state, the country, and the family I'm in. I need money to move in with a friend in the UK who I know will help me de-stress and help me get into a group home and get a job up over there. My mother keeps saying she'll get me medicated for my stress, but she hasn't done that in several years. It would probably be cheaper to get medicated in the UK anyway, but I need the money for the passport and ticket as well as a bit extra to hold until I can get a job and work visa, so please help however you can, I really need this. My mom's boyfriend is also a violent psychopath. He's currently after my sister's boyfriend, but who's to say I'm not next.
