Welcome!
Well, I agree with purpleteacher. It could be any number of things. But, if it was me, I would steer clear too.
You are experiencing the lovely panic attack. I HATE them. I can trick myself into thinking I am ill as well. I used to have a very high number of panic attacks in one day, every day, so I know that they are hard, and emet is hard. I, too, have had this since I was little (2years old), and I am 28 now, so it's been a while.
I think most of us here have had our share of depression and self-injury, if on;y to make the panic go away. Go to the 'treatments' thread on the main page, and there is a wonderful document in there by Sage. Print it. A few times. Take one to your shrink (I can't spell the proper term....lol) Give one to your mom, if you think you can. It is very informative, and will give you a really good picture of what we all feel and it is comforting to know there are others out there like you!
Anyhoo....good luck, and hope to hear more from you!
