Going through strange chest pain, but can’t afford to go to the ER.

I think this happened to me once before. Don’t remember it being this intense though. Not sure what the cause is, but I feel like it’s related to my stomach (could be a digestive issue, considering that I haven’t had to poop in a while despite eating food. I also get bad stomach acid and may have GERD.) But anyways, I’m worried it may be a heart attack or something else that’s bad, but it hopefully it’s. It’s been a little over two hours I think. I am going to try and get some sleep and maybe in the morning I’ll feel better. I can’t really afford to go to the ER, or any doctor for that matter. So I’m kind of just waiting to see what will happen I guess. I can’t describe the pain like this: tightness in my chest like someone is clenching it, along with a slight burn as if either stomach acid was acting up or there were something lodged.
