Does anyone suffer with actual heart pain through upset, stress or depression?

I had a rather scary episode at the weekend experiencing real discomfort around the heart area. It was bearable but to be safe I rang 111 and they sent paramedics. I was checked out in hospital and given the all-clear yesterday. They were 99.9% certain that my heart was not at fault but could not help with finding out what caused it. Realistically, it could be anything, I know that.

However, I had quite a lot of emotional upset on Friday and Saturday. I am also quite exhausted at work. I wouldn't say that I feel particularly stressed and can happily have a laugh with friends. But what damage underneath? Could emotions have caused the pain? it happened in the middle of the night while sleeping.
