We all are gonna have bad days.

Just get back up on the horse and keep doing what you've been doing to lose weight.
Today, I went in the freezer to have a bite size Hershey bar that I knew was in there. I never crave chocolate, but today I felt like having a tiny piece. I searched that freezer over and none to be found. I was mad! My kids found it and ate it. Not fair... that was emergency chocolate!
That was nice of your brother to work out with you.
I hope you have a better day tomorrow.
