panic

so today i go to put on my favorite £40 topshop jeans, that were a teensey bit too tight for me when i bought them, and they were too big. and a stretchy top that is usually tight fitting was baggy. i threw them straight into a washing machine thinking maybe that would shrink them down a bit - will have to see when they dry.
i tried on my favorite LBD that i was forced to get in a (UK) size 6 because that was all that was left on the sale rack, and it fit perfectly. it's made of stretchy material so i could always fit into it, but only just.

and the scales this morning said 110.5 pounds. my target weight was 112.

i suppose this is okay - i can allow myself to fluctuate between 110 and 112. but the thing is, the amount that i am still eating is the amount i need to lose weight. i need to start eating the amount i need to maintain weight, but my calorie calculator says that's about 1600. that is so much more than I've been used to - more than double, about triple some days! how am i going to suddenly get back to eating that?
i thought that i would ease myself in, so i was going to have a salad sandwich for lunch instead of just a salad. but i couldn't after the donut that i ate yesterday.

I'm not sure how the best way for me to do this is. i suppose increase portion sizes teeney bits at a time? my body (and my mind) has gotten so used to restricting, it's going to be hard. but i don't want to carry on losing weight, i just need to get more toned. my boobs are small enough as it is and i think they're starting to get smaller! guhhhh
