I’m 19(m) and play a number of sports so I should have a healthy heart yet I keep having feelings that I’m gonna have a heart attack or my heart is gonna stop or something. 

Sometimes I experience pain and or tightness that can happen for a millisecond or last a couple minutes but most the time it’s just worry and anticipation of the pain.

It’s made worse by exericse, caffeine, weed and anything else that I feel could have some negative effect on my heart. The anxiety is different for each of those but my thought patterns are the same.

It never used to be like this. I used to be able to chug 4 energy drinks in a day chill and now barely manage 1. I did way more longer exercise in the past and at greater intensity then I do now. And weed used to be ‘the more the better’ but now just one hit screws me up. I also believe it was this one time on weed that triggered all of this :(

I’ve had it for 2 years now. It’s become so crippling. It’s destroyed my confidence and leaves me feeling fatigued and burnt out. I’ve tried CBT, anti-anxiety supplements and I have a good diet but it’s still here. Can anybody help me?
