madisontaylor- Psych central is a great place to get out some of your thoughts, especially if you do not have some where to go to get them herd- but with you being 15 and you are in school- is there any way to talk to a counselor about this stuff. if one thing i wish i would had done different it would be to have starting to get help earlier than at 24 almost 25... family issues as a teen and mood swings, and bad thoughts, I would not think to take lightly... I hope you the best and that talking to your mom goes well.

hugs your way and best wishes
