I think I had a mental breakdown or burnout about two weeks ago, it made me more depressed then I am already, about a week ago that went away, but now the other symptoms are still affecting me, my memory is almost non-existent, I can't seem to learn new things, and my concentration is so low I can't figure out simple math problems, this is bad because I'm in my last year of high school and can't do my work, even if I try. Will these symptoms go away or will they continue?
