I don't want my parents to find out if I do tell someone. My mom won't tell anyone because she needs to be loved and she has depression and she doesn't have the courage to stand up to him. I know that I can't take it anymore and I always cry myself to sleep. I don't see what the point is to live anymore. Who should I tell though? There is no relative that I am very close to. Also, what should I say to them and how do I start the conversation?

You need to keep your post on one thread

Yes you need to tell somebody that you feel you need a therapist. Start by telling a school nurse and tell her all your problems with how you can't cope.

Have you read the replies to your other thread yet?

I believe that those answers basically answer this question.

EDIT: Oops, we posted at the same time, down to the minute N0help! Had to StR though.

Do you have a girlfriends Mom that you can talk to?

If so I would say.I'm having some family problems and I need to talk to someone about it.

That's all I would say.

My friends kids always talked to me, they still do.

If not ,anyone who you trust sweetheart is a good person to talk to.

I think if you involve others your mother will have no choice but to stand up for you and you would be helping her as well.

It's a very hard burden you are carrying.
Talk to someone you trust.

You deserve to have a beautiful life :)
