I went to my Doctor and had every test known to man.
Everything was normal.
Before he did any test he told me that he really thought I had a panic disorder, but he wanted the tests done anyway just to be sure.
So that's how I know.
Just finding out that I didn't have some kind of a life threatning illness was a major weight lifted from me.
So my advice to you would be to just go to your Doctor and have tests done.
Test's for your heart, blood sugar, thyroid..the whole nine yards.
