You need to check this with your psiquiatrist, I was a decent student as a kid, got admitted in college and everything, but after my crisis I just felt like retarded, couldn't understand or process little things, I failed miserably at things I could do a few years back. Gutted me but quitting was the right choice, and in a family of proud graduates I felt like a failure. Actually I don't even try to read becouse my attention span is terrible. It's something I have to learn to deal with. Anyway don't t lose hope. Ur case might be different. Hugs!
