I have panic attacks all the time usually because of school in general. i am really angry at almost everything. what is wrong with me?

Uncertain.: I am not sure but you could have a mood disorder (like depression) in addition to your anxiety disorder. I recommend seeking psychiatric evaluation if you have not already done so.

You may be depressed: Or simply overwhelmed. Seems like you are going through a rough patch at this time. Anxiety related to school could be caused by so many things including, grades, peer relationships, and school phobia to name a few. All of these could result in severe stress or depression but luckily there is help. See a psychiatrist for an evaluation. Good luck.
