hey. i'm struggling too. you have been though a lot, and the bulimia has probably gotten worse becuase of it. i know mine does though situations. it is possible to die from bulima, but from the sounds of it it just sounds like your stomach is haveing trouble with over producing stomach acid because you have been purging so much. people with bulimia can get heart attacks from it. ive had several signs of them before, the aching arm, the heavy chest, the left ring finger tingling, but my heart has never stoped. im lucky. thats hasnt happened in a long time though. i'm not a doctor, and i know i cant just tell you to stop bulimia beacuse it doesnt work that way, but try to purge less if you cant, or maybe take tums to help stomach acid if thats what it is. your post was vague so im not sure
