Bella, panic/anxiety attacks will go away on their own. The body will only release adrenalin for so long. Adrenalin is needed for an attack to happen. If you're relaxed, you're not going to have anxiety or panic attacks.
Begin changing what you tell yourself during an attack. I imagine you're adding fear which prolongs the episode. Use positive self talk during the attack. Try to distract yourself or lie on the couch as relaxed as possible. Sometimes I'll lay there like a rag doll.
Do you have any idea what is causing your panic attacks?
James, you did great by going outside and trying to walk it off. It probably would have worked if you kept at it and stayed positive. Thank goodness you have a brother to help you with these terrible feelings. I used to go to the ER when I was first having the attacks. After awhile, you recognize what's happening and learn that you're not going to die.
Find a great psychologist and try an anti-depressant. Life will get better
