I don't Get It

I don't get it.
I have lost total connection.  I feel like, what I guess, an alcoholic feels like "the next day"  - "Im never gonna drink again."
Only I say, I'm not eating cheese again.  I'm not eating pepperoni again.  I'm not drink wine again (caloric worry, not the alcohol part).  Chips will never touch my lips again. 

I also feel like Scarlet O'Hara (without the 18" waist) ~ Tomorrow I'll exericise.  Tomorrow I'll eat better.  Tomorrow I'll say No!  I'll worry about it tomorrow!

What the hell is wrong with me?!?!
