Can someone advise what I am experiencing? This has been happening for years but Im just becoming very conscious of it now (I'm 27).

I'll be doing something, like reading, cooking, driving, showering, whatever - and out of no where I'll get a kick to the guts of nervousness, like as if I was about to go on stage and perform or something.

It happens ALL the time, kicks to the gut of nerves and I'm just doing normal every day mundane stuff.

What is this??

Also yesterday when I took a light 20 minute power nap, I kept waking up because my heartbeat was racing and the nervous sick feeling was coming and going..
