another day down the drain

It's like once I broke things yesterday and drank and purged, I can't stop. Today I did it again. I just need to lose a few pounds that i gained this year. And im not binging and purging, I ate a salad with turkey and cheese and purged it. I feel that my body doesn't need nutrition right now because it is at a higher weight, it doesn't feel exhausted and it has energy. So i feel as though i am allowed to restrict and purge for a little while. At least until I start feeling sick again.
 
I have a fucking exam tomorrow yet all i can think about is food and my weight. This is ridiculous.
