Help me please, i think im suffering anxiety or depression?

FIRST, you do know this is not your fault don't you. It's not just what adults tell their kids, it's TRUE. I would guess you are more angry than anything else. And depression is anger turned into yourself. You need someone you trust to talk to. School is out, right? Then try to talk to a friends Mom or Dad and see what they think you should do. Don't carry this around inside you alone. You sound like a great guy who deserves love and attention from your parents. Don't go do something stupid just to get their attention. Talk, write a journal, talk, talk, talk.....
