This feeling of something bubbling inside my chest, its growing and getting harsher and could explode any minute, i cant focus or do anything, its too intense.

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

For 3 days I had a feeling that came up pretty often and I cant name it, I dont know what is it and the more i try to see what is it the more i feel worse. Usually letting feeling be and letting yourself experience it helps but not with this. I find myself feel grumpier, triggered and more angry. Its a mix of fear, but then i get angry too and I dont find letting myself experience it helpful cause I just stuck there. It feels like its in my chest and when it gets triggered it makes things hard to enjoy. I tried to be kind with myself and see what causes it but trying to be kind with myself triggers this annoying feeling and it just gets worse... i dont know what helps thats why i ask your help, if you ever experienced this... also i what i almlst forgot to mention, what is really important is that i became really sensitive to every thought, and any thought can trigger this feeling or any thought can trigger a negative feeling that will trigger this feeling. And honestly the "just accept it and let yourself feel what you feel" doesnt helps here cause i find myself really angry that i have to let myself feel the emotions that are triggered by these intrusive thoughts...

im so scared that this is just denial and that im actuall gay. idk what to do anymore i need help. its just constant anxiety in my chest and i hate it. is there anything i can do to help?
