Hello, i've got a bit of a pickle here. I post on this forum and I am using this account because my issue is slightly embarrassing that I do not want associated with my normal account.
I think I am experiencing mental deterioration in mathematics and sciences, or a psychological version thereof. Even though I try harder, the same problems I solved a year ago are now impossible.
During high school, I could look a problem for example a limit, and comprehend its value. Derivatives, trig, chemistry, it all was no problem and I was an A student without a lot of effort.
Around college, things changed. The problems I am doing are the exact same as the ones in high school. Even though I study day in and day out to my utmost ability, it seems like all I do is lose focus. I feel as though I have lost my ability to comprehend why and how something works. I feel in a constant stupor, and simple mathematical operations I could do in my head now take me several lines of paper. When I stare at the problem, my brain seems to shut down, and all I do is concentrate uselessly until even my vision is blurry.
This is very frustrating and a lot of my classes are at the point now where I have to make excellent grades in order to barely pass. I have always had an interest in engineering (my major) and have undertaken many projects on my own will. I still enjoy the sciences.
What is wrong with me, any help would be appreciated, even humor.
