I feel so odd today I woke up 3am and felt like I was "dead" I stayed up til 5am and then finally fell back to sleep , woke up about 9:30am an still felt odd , had the slight shakes all day, been having some trouble seeing, I feel like I'm not breathing although I am. Everytime I blink I feel like I'm going to black out.  It's now 9:30pm , I've been on my period for 9 days and my periods are very irregular , could it be my period ? I'm going to try and sleep it off again. And head to the doctors if not better tomorrow.
