Heres the deal, approximately 6 months ago I began feeling abnormal. I started getting symptoms such as problems concentrating, pain/irritability in my head (mostly back or front of head), random heavy breathing, and feelings like im gonna pass-out for no reason. The concentration symptom randomly shows up, but is expected now when i do certain things like read, watch a movie, sit in a class, or play a video game. The pain/irritability seems like its there most of time along with the heavier breathing. The feeling of passing out is not all the time, but I've noticed it to be present while doing things like speaking in front of a group of people or even driving my car, I feel like I am going to lose control of the car and go off the road or something. I have found a couple of things to be helpful in those types of situations such as eating sunflower seeds, and pinching myself....yes pinching myself to get myself to concentrate on that instead of the feeling of passing out or losing control. When I first really started to notice it 6 months ago, I went to the ER and they diagnosed me with a panic attack. I havent been to the doctor since because I am in the military and am scared of being medically discharged or something. I have been living with this ever since with no medication or anything and I am starting to think something is really wrong with me. Please advise. Thank you.
