I am currently going through this. It is hideous!! no one really told me!! I am hot, I suddenly start sweating in class and feeling overwhelmed even though I am wearing a t shirt. I seem to get memory loss (for names of pop stars or trivia in mid-sentence) my TAs probably think I am nuts! I get depressive thoughts at night especially and see everything as pointless! Then I am back to normal for a short while, before it all starts again!! Any advice?? I wonder if I have grown two heads and feel self-conscious in school!!
