im 16 yearsold, ive been purging my food for just about a year now, recenty ive noticed my heart racing, and a fluttering in my chest. i dont know if this is because of my ed, but ive had a kink in my neck for 3 nd a half weeks, and the whole left side of my body spasms and hurts realy badly, especially my stomach. its just little twitches everywhere but is extrememly painful, this has happened 4 or 5 times in the last month i think. i dont know what this is, but i dont wanna die from this, i need to know if these are warning signs of something.
