I'm scared to death! I finally fell asleep after crying and being a little upset missing Hannah around 10:30. Well I always pee before I go to sleep and I did. Well at 11:30 about an hour later I woke up with my bladder feeling very full. Like I'm about to bust. So I get up to go to the bathroom and didn't even make it to my bedroom door when my left leg went completely numb and I hit the floor....I got dizzy and very hot and felt as if I blacked out the way I hit the floor! It scared me so bad and now I'm wondering what happened??
