you asked: Help what is wrong with me!!
courtney--- you have an anxiety disorder. this is causing your mind to run in circles. this causes your nervous system to be hyper excitable---which causes strange sensations---including limbs, fingers, toes, etc to feel weird. it causes twitching, tingling, buzzing, burning, prickly feelings, itchiness, crawly feelings, cramps, hot flushes or cold flushes, limbs fall asleep easier, feeling weak, jelly like legs, arms/legs feeling tired worn out.
how do I know? I've had every darn one of those things. and I've seen many, many people over the last 5+ yrs on this site worrying themselves to pieces over the same things.
you can believe me or not. however whether you do or not does NOT change why this is happening to you. You have an anxiety disorder that has gone VERY physical on you.
the big thing you have to do is decide how you want to deal with all of this.
