I would suggest if your still at college and they provide testing then to put your mind at rest get tested, its nothing to be scared about, i seem to get on ok with my life even though i have dyscalclia and dyslexia, i am a qualified vet nurse and dont seem to have any difficulties so even if you have got it you can still occomplish many things
Maybe there is someone at college who can point you in the right direction, ask someone if you can, ggod luck
