I haven't eaten in a week?

Yea I understand exactly where you come from. I am not meaning to harm myself but even though i know what i am doing is dangerous. I am not trying to die..I am just testing myself to see how long I can go for and I feel amazing when i look at myself in the mirror and see how good I look, I am quite proud of how skinny I get its achievement for me..I was 5'8 and at my lowest 100lbs. I didn't think I looked bad at all..but it goes in cycles.I been eating the last two weeks or so and only gained about five pounds..now i don't eat like a normal person I eat about one meal size a day..granted or less
