Lifes hectic

Just thirteen years of age,and in a life of hell,sister committing suicide, brother should be in a cell.mum coping w/ depression,and raising 3 kids on her own,us kids never help her,nag nag nag moan moan.then i started cutting,but i must keep it a secret,because i don't want people to know,that I feel like sh*t i don't know y because it helps,but i guess thats just me,don't want people to judge, so I just don't let them see.But lately Ive been having these thoughts,Wat would happen if I take my life?I'm sure it wouldn't hurt too much,Just one slice w/ my knife.
