i think i may have low blood pressure, my face sometimes goes numb, it get nauseous, and i feel like passing out, it could be dehydration but it gets worse when i get sick like when i catch the stomach flu, and when i get to hot because of the summer heat, the only thing i can do is try to find a place to lay down usualy whatever is closer and its usualy the floor, but it feels like i need to lay down flat and i cant sit up i have to be laying down its the only way i can make it feel better. it feels horrible.
