wow does this sound familiar. when I was 17 I weighed 180 lbs. something in my brain snapped and I stopped eating 6 months and 55 lbs later Idestroyed my metabolism. I started to eat again and the weight came back on thats when I went bulemic and stayed that way for about 5 years. I find that I do well on low carb and I finally feel like my metabolism is working for me and not against me.
I feel what you are saying hang in there. LCing has given me my energy back.
