I'm going away for the night with my boyfriend, to a cute, expensive hotel, it should be wonderful, so why am i freaking out?

Ive packed and unpacked twice, Ive changed my clothes three times (and counting), and now hes gonna pull up outside any minute and I'm on the verge of a hysterical tantrum because i feel too fat to get in the car and spend a romantic weekend with this guy who thinks I'm everything that I'm not. Somehow Ive fooled him into thinking that I'm a normal, functional human being, where in truth I'm one low fat cracker away from a total melt down.

Panicking now. Pacing. Praying even. How am i gonna get threw this?

I'm aware of my area, the amount of space I'm occupying, volume, measurements, inches, pounds, ounces, maths? I'm counting, continuously and methodically, adding, balancing, and i cant do this if I'm with him, in a different environment...

room service
alcohol
lunch
dinner
breakfast

and no way out. I cant do this. I'm either going to seem like a total idiot, or become an emotional wreck, a tear-streaked, fat mess.
