you should go to the doctor for a full workup to see the damage you have done and whether it is reversible. you do not mention if you abused laxatives as well but my sister never bounced back after years of abuse to her body. her intestines could no longer function correctly again and she went thru many operations removing parts of them where food rotted inside of her because it could not digest on its own. she can barely eat solid food anymore. her systems are shutting down on her. she is not expected to live more than a couple more months from all the damage she caused. she is only 48. she hasn't been actively anorexic for over a dozen years. but she continued to have problems with her potassium levels and other things because of it. so please, go get checked out and take care of yourself before any more damage takes place.
