Breathing

I just had a really awful chest pain that felt like my chest was exploding and im really terrified. I feel like maybe it was a heart attack but idk. I've had many ekgs and a chest x ray and they don't find anything wrong with me. Idk what this means anymore im so sick of being scared that ill die. Can anyone relate at all? It comes out of nowhere

Does anyone struggle with feeling like their ocd issues are not ocd enough compared to other peoples ocd? Is this an ocd thought itself lol

Does anyone else have panic attacks almost everyday??? If so do you have a strategy to help overcome the panic attacks. I could really use some help 😥
