~It doesn't sound like you ate that way before you purposely ate that crap to gain weight. It's okay to concern yourself with your size and calories. It's your body, be aware.

43 pounds in a month is very extreme. You should lose and gain slower than that. No wonder you're miserable.

I think you should increase to at least 2,500 calories and eat some of the things you like sometimes. Don't reward yourself by eating those fatty foods, but depriving yourself of them will only make you gain weight trying to replace it with other foods.
