I have the same diagnoses, and everything you've experienced. You can have that, what's called "Free Floating Anxiety" where it never escalates to a full-on attack; you just have this ongong anxiety that's obnoxious. I have had the bad feeling/ache in my stomach off and on since I was a teenager. I used to think soemthing legitimately was wrong. Now I know it was anxiety, even back then. Oh how our bodies know things we can't even conceive.
Just wanted you to know I am right there with you. I've posted a few threads in this forum about anxiety...maybe some will help.
