Hi there:
I am an 18 year old male. First of all, I have never been able to completely express this problem I feel to anyone. It's very hard for me to describe it, so I'm not sure whether this will be completely precise. About a year ago, in a certain class, I experienced a wave of "stupidness", and not because the class was complicated

. Let me explain. At that point, it was like I lost the ability to think as well as I usually do. I felt completely stupid and uncoordinated. Ever since then, I have been experiencing these little "attacks" once in a while, but whether I have them or not, I don't feel as coherent and able to think right as always. Little things like: it's hard for me to find the right words for something, I mistake some words for others, I make simple mistakes ALL THE TIME... are very common for me. I am worried that I might have some problem, because not only doesn't it go away but (maybe I'm just paranoid) it keeps getting worse and worse. It's like I'm losing brain functions, or they are getting deteriorated. Everyone tells me that I'm just paranoid, but I really do notice this. I don't think like I used to. What can I do?
