Why do I always do this to myself?

I bought slim fast powder and these drops that you add into your drinks to lose weight. I know I don't have to lose weight but my stupid brain is like yes you do especially if you are going to dance. Nobody wants to see that wearing skimpy outfits on stage. You'll make everyone throw up.

I think it's because I ate my entire plate at dinner tonight and maybe that's why I felt compelled to shop on amazon.
