Please don't smack me

Okay, so I've been losing a little weight lately. Last time I was weighed (a year ago) I think I was about 125 and a size 6. Last week I bought size 2 and 0 skirts at the Salvation Army. Today I bought size 2 capris at Target--and usually Target clothes run small. I'm thinking I must be down below 110 now. The other day I was wearing size 6 jeans and, without thinking, pulled them off without unbuttoning. Yeah.

Putting aside any "Fuck you, you skinny bitch" thoughts you may have in your head right now (LOL), do you think that's getting unhealthily thin? I'm on the fence about this. I haven't been this thin since elementary school (srsly, I wore a size 5 in 6th grade), but then again, I still have B cup boobs and don't have terribly visible ribs. It's just kind of weirding me out, as I haven't been trying to lose weight (why would I?) and while I have been eating less than I used to (hello, being poor), most of what I do eat is pretty damn fatty. Lots of cheese, ham sandwiches, ice cream, frozen pizza, etc. The weight lost seems to be coming all from my waist.

THoughts?
