Am i mad at the world? What can i do to help myself?

the best thing you can do is think about something to take your mind off of these things, but if this doesn't work then you must see a doctor, perhaps it is something that can be aided with medication, or perhaps it is something that can be helped with counseling. for now, just try to stay busy and take your mind off the things that make you angry. however if the problem persists then i would strongly advise your speak to someone.
