How did you end up in the end and how did it affect you later if I may ask?
I mostly got back to being capable of doing the math problems again. I had to retake one course and went on acing the final for it with a 98%, etc.
Years later I've largely recovered, but I still shy away from basic arithmetic in front of others. However, I was able to get back to where I can solve math problems and even find it fun on the rare occasion I get to.
In some ways I have a deeper intuitive understanding than I did as an undergraduate, despite my faculties not being quite as "quick". Actually I rarely need to solve an equation to get enough of the answer I need to solve many problems.
Luckily I had a friend who knew I was capable of it and pushed me a bit to get through it, but it was exactly like a trauma block. Well doing quantum chemistry research as an undergrad with a crazy Russian professor will do that to yah.
