getting started!

i'm ready to get back on track with this. i've had 630 calories today, which i think is pretty good for my first day of really getting back into this. i have so much motivation now that i've seen the spring break pictures. my bff is gaining weight like its her job, so my hope is to be skinnier than her by summer :) she's always been smaller than me, and i'd love to beat her! any suggestions on a calorie plan to get started on? nothing too hard, my main focus is control right now !
