I constantly got this feeling that there is something going to happen to me, like heart attack and the earth is going to end. I overthink also like im super not healthy, then it triggered something in my mind and start to feel different, i feel not good and i want to cry out those feelings that i cant explain (i really cant explain) and I do feel some shooting pain in my left chest. And when i do start feeling one of these, i feel like im going to vomit. After vomiting (tho i throw up nothing) i feel better again. There is no day i didn't feel like this. I overthink then i feel like im going to vomit. sometimes it happend twice or thrice a day. So to feel better i tried to vomit. 

Ive been in cardiologist and my findings are normal.  Am i just paranoid? Do i have anxiety?  Sorry for my grammar.
