I don't know if I actually have depression or anxiety, but its been really difficult to concentrate on things lately. My grades have suffered drastically. I feel tired, both mentally and physically, all the time. Things that I adored doing seem too hectic. My memory seems to be getting foggy. General things that I had discussed with someone over the course of the past few days/hours, or the directions to my home, or what I study for my exams, it takes a while to recall things like these. Sometimes I can't remember anything at all, even the childhood memories that I used to be able to recall quite easily.
