just wanted to ask someone else, is it possible for years of stress, anxiety, depression to change the central nervous system to make it sensitive to pain and thus even create nerve pain?

I had an episode in 2013, a tiny infection in a tiny cyst created excruciating nerve pain, it then got worse with paresthesia, electric shocks, stabbing, I couldn't even walk.
Once I took amitriptyline and lyrica it went away..I was able to go off them and had 1 year and 4 months with 0 pain..it returned 2 months ago after severe stress.... I used to think I have nerve damage but now since I had a LONG time with no symptoms it can't be damage, right ?
I don't have a neuro to ask and my GP thinks I'm an alien but my symptoms are real :(
