I have gained 20 pounds in the last 6 months. I no longer have clothes that fit, just my old sweatpants. I wait until I'm really hungry, then eat til I'm ready to explode, which leads to MAJOR guilt. Sometimes I try to throw it all back up. I'm usually unsuccessful(my most success is in the morning), and just end up dry heaving for about 5 minutes before giving up and crying. Recently I tried NOT eating, and wound up with blood sugar so low I couldn't walk, needless to say I fixed that by eating... and I ate too much. I don't know what to do...
