Well, as a hypoglycemic I'll say that what you describe sounds like a sugar crash. I keep a stock of glucose tablets on hand for when I start feeling low, they're available over the counter and are just sugar tablets so they don't have any adverse effects or anything. Maybe you could check into those? Even if they did just have a placebo effect on you, it's better than nothing. I'm sure you'll be fine, just hang in there and go to your doc for a work up if you're unsure about it all.

Also, have you thought about looking into medications/treatments for anxiety? They help me with my issues (I was once convinced for two years that I had diabetes and the doctors were just missing it... Even tho my sugar levels were always in the normal to hypoglycemic range.)

shannonmb, wow, you and I could be twins. That's exactly how I am. I'm the kind of person that actually holds my breath to make sure I can feel/hear my heart beat at night because I'm afraid it might stop. :/ It's a sucky way to live, most definitely.

I do take Adderall for ADD, and it helps with my anxiety too, but it was so late in the evening it had worn off. I don't know what caused the sudden anxiety. I'd like to see a therapist, though, but I'm not totally sure about it yet.

And Latchkey Princess, I'll definitely look into those. I didn't know they were JUST sugar, so I never thought to buy them. I figured maybe there was something else in them.

Wow, this was me. When I started running and jumping rope at around 22 or 23 I would stop when I got this unfamiliar pain in my chest. I could have sworn I had arrythmia or something that would kill me if I didn't stop. I went to the doctor who told me that I was perfectly healthy and that I should drop a few pounds (which made me mad because I had already dropped 50 and loved where I was and she was a stick). With the "doctor's okay" I continued to exercise and eventually the pain went away.

Now I'm at the cusp of 30 and though I probably should be a little more anxious I'm not because I've somehow acquired this "what will be will be" mentality that would have been an anathema to me even a few years ago. This, of course, does not mean that I will not fight for my health in any way I can but there are something that just happen.

Coincidentally, today, I started doing interval training again (not quite HIIT but close) for the first time in years and that old familiar "chest pain" came back. Only this time, I recognized that I was pushing myself and it was good. It will eventually go away and I would be the stronger for it.

I still get anxious about some things but not nearly as many. I think it's part of the second guessing your "health" confidence. Like "I know I'm healthy, but what if I'm not?" Constantly hearing horror stories of people dying of undiagnosed diseases/conditions does not help in the least.
