I'm so tired of how low-functioning I've become, I can't remember 80% of the things I learned/experienced, to a point where it embarrasses me. I used to know so many facts and be truly passionate about different topics, now I can't remember what I read about 2 days ago. It makes college so difficult whilst I feel like others have it so much easier. I used to be the gifted teenager/kid, now I'm just the shadow of it, completely unable to concentrate.
