I'm getting worried because for the past few nights I've been feeling really really strange. my body parts feel numb and I feel incredibly confused like it feels like im in another world, my whole body feels so unexplainably weird, it's horrible, I have a sharp piercing headache. I feel like I'm going to die from it one day and I don't know what it is. Any ideas anyone? Feels like I'm about to die at any second or in my sleep.
