...wow...you do have a lot of things going on right now but that does NOT mean that suicide and running away is the right thing to do. Take a step at time, a breath at a time, fix things one by one. Help your cousin out first.
Talk to their bully-try to settle things (that doesn't mean beat them up) I mean talk to them. Your grandma went to rehab because it was her own fault, NOT YOURS! So forget about your grandmother and think about you!
Calm down your mother and talk gently to her. Even if you are right, make her feel like you surrender. Your father is a another deal.
Leave him messages on his cell. Tell your mom that he isnt talking to you- txt him send him e-mail messages. I wish you so much luck!
And please please pleeeease! Have will power. Will power is the key!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
