I am a 21 year old female. Yesterday I woke up with extremely blurry vision and double vision, my body extremely weak, I've been having heart palpatations (to the point I feel like I'm going to stop breathing), I am having a hard time remembering things, my balance is really off. I find myself running into things, and there's a spot on my left arm where you gently touch it and it feels like someone is poking me with needles. I really need your help. I'm really worried!
