It can happen yeah. I recommend some anxiety medications if you can. I'm in buspar which isnt perfect but its been much better

Yes anxiety stress infact from our brains affects our bodies as in your chest and stomach appetit mood all that it's pretty awful :(

That happened to me around July 4th. I got some bad news and I geuss it's what led me to expirence my first panic attack and it sucked. Lowkey though I was dying.

This used to happen to me a lot! I got over it by saying I'm not having a heart attack, I am healthy and young or whatever would apply to you, unfortunately I did gain different symptoms after getting over that fear but hopefully it works for you as well. I can't tell you how many hospital trips I made before I got sick of it and started convincing myself I'm okay
