Hi ! I’m new to this community, but not new about anxiety !

I have a general anxiety disorder, as well panick attack disorder. But today I was at the store, and felt a kind of tightness in the middle of my thorax. It was not hurting , but I comfortable. Obviously I start panicking and got out of the store , took a few breath and after 2-3 minutes it was gone. 

But now here I am wondering if I just had an angina attack ! ( you’ll guess that I have health anxiety too). It’s just I never felt that before. 

Does someone had those kind of symptoms ? 

Thanks in advance !
