You don't say how old you are or if you are in school. If you are attending school, go to the school's counseling services and talk to someone. Or a teacher you feel you can trust. Find some responsible adult to talk to about this.

If you are old enough go seek out professional help yourself. Find your local community mental health clinic, look in the phone book, call the village/city services and ask where it is. You should be able to find a mental health clinic that offers services on a sliding scale. You may even qualify for free therapy. Go find help for yourself.

Chances are good all the adults you live with won't want any part of it and will be angry that you do this. But they are sick people and are not concerned with what is best for YOU. Go get the help you need. Good luck.
