laydee,
I'm diagnosed with a few mental "disabilities", in the current medical sense of the word. I'm interested in math, and there's a decent chance I'll became a mathematician. I'm very weak in any kind of computational math, but am exceptionally good with abstract math.
If you want to ask me any questions, feel free here or send me a message. I can tell you right now, when I was in high school I couldn't do the math (ditto for the stuff in the first 2 years of university). But from there on out it was fairly easy and extremely enjoyable for me. I would have never known if I'd just thought "I can't do this" and gave up when doing garbage calculus style math.
