welcome!! i am pretty new here too, but i've already found a lot of support here. it's really amazing. i know what you mean when you say you feel like you woke up one day in a strangers
body. last summer i was a size 12 (not my smallest ever, but smallest since i had 3 kids!) and now i'm barely squeezing into a 17! i think about my weight constantly too. you would think that would make it easier to make smart choices, but it doesn't always for me. anyway, you've made a great decision and that's the first step... good luck!!!
