Someone Put Perspective On My Anxiety, Please?

I haven't been diagnosed, but i'm starting to make sense of what's going on in my head.

A little over a month ago, I suffered a very bad [and also shocking] allergic reaction to aspirin. I remember experiencing hyperventilation for the first time in my life and thinking that I was going to die. Not fun.

Used to being as healthy as a horse for as long as I can remember, my brain derived from these experiences the realization that my body is not invincible, and a i'm a potential walking health tragedy. Ever since then, i've been experiencing:

sharp, quick pains on the side of my head
sharp, quick chest pain [although this has only happened once or twice, and far inbetween]
low energy
bouts of frequent near-lightheadedness.


Those are always combined with me mentally telling my body to stay calm, not to panic, not to worry, and not to hyperventilate. Of course, the anxiety is nearly impossible to get rid of.


Then again, other side of my head tells me that i've self-diagnosed myself with anxiety disorder, that there really is something physically wrong with me, and that i'm making it worse by writing it off as being mental.


A vicious cycle, isn't it?


My boyfriend told me that the paranoia following my illnesses along with the instablity of the move-out process [i'm going away to college come fall for the first time, adding a numerous list of worries] could be triggering my anxiety.


What do you think? Is anxiety disorder a floodgate that once opened, stays with you forever? Or is it something that can be kept under control when you provide outlets for the stress?

Should I talk to somebody about it? Should I go get another physical? Should I take yoga?


I want to go back to normal, and enjoy life worry-free again.
