Wow!! I just joined this forum yesterday & I have read your story. You are the strongest teen I know!!
A quick note on the abuse & not getting help - my husband and his brothers were abused by his Mom - beaten with belts, stabbed - starved, locked in closests - tortured - it was terrible. This is when he was a child.
He is 65 years old now - he never told any one. In fact, his Mom is still alive & came to our wedding 15 years ago - had I known - she would never have been invited.
Now - all these years later, that abuse is causing him severe depression - to the point a few weeks ago - he wished he was dead.
Now he is in therapy & has a lot to process. His doctor has placed him on a levae form work - and he may not return as he is that ill.
I'm telling you this because I don't want to see your future clouded over by this. Get the help you need. You have already done the hard part.
Good luck!!
