I have Seasonal affective disorder but I also feel empty every single night, I just get the need to cry and just end up laying there. I have fainted 4 times all last year, but this year I've been getting what I looked up to be called "intrusive thoughts" in the middle of class I just get a 1 second image of bloody hands pop up in my head out of nowhere. I have had more since that one related to gorey or creepy things and I barely remember them.
