What can I do about this chest pain?

I've been having chest pain on and off for almost two months. I made several doctor appointments, and it turns out that I have pretty severe anxiety. Other doctors said it could be muscle pain/spasms and musculoskeletal pain (it is NOT heart related).
I take Naproxen, Tylenol, and Ibuprofen interchangeably (NOT at the same time), and it works, but the pain ends up coming back the next day. If I keep taking pain medicine, my body will become immune to it, which Io think is starting to happen slowly. What are other alternatives?

I also get shortness of breath on and off every day fever since Mid-June.

My anxiety is so bad that I even have bad dreams- like last night, I had a dream that my sister died. I also have frequent dreams of bad things happening to my mother.
