I'm having an off week

My hunger seems out of control this week big time, somethings that I rarely ever have, have been sneaking their way into my house. Like Donuts, and Ice Cream.
It's insane, I feel I like I've lost it and I have failed. But have I? I may have goofed, but how bad am I?

I was feeling sick this last weekend, barely ate. Is this the cause of what seems to be uncontrollable hunger, eating until I'm stuffed and wanting to eat more. Weird. I don't like this.
I'm thinking maybe I didn't have enough water, or enough fruits and vegetables. That could be it.
Is it just in my head...I hope soo. I haven't slept very well at all this entire week.I haven't been able to go to the gym this entire week. Oh my goodness, I'm being a very bad girl.
Maybe exercising will fix this problem. I can't go to the gym tomorrow, but I can go running. Must go running. Must go, I cannot fall backwards.

I'm also very afriad to weigh myself. Not good at all, and May is coming fast.
