Teen depression PLEASE help!?

I'm really sorry you are having a troubled domestic life. Have faith, everything passes with time and this too shall pass before too long. You are going to have a better future. Make sure your mom is getting medical help for her mental problems. Make sure somebody is home to look after your mother and you go out more to refresh your mind. Staying home all the time under those conditions are not healthy. Go out, develop a hobby...you are going to have a wonderful future I promise.
