Had a mini cupcake today, feeling a little guilty

One of my co-workers was selling cupcakes to help fund her Mother's mission trip to Uganda. So a lot of people bought cupcakes and they were everywhere. I haven't been eating sweets for several months but, today I just had to have one. She is a great cook and baker and in the past I have indulged in her treats. I am feeling a little guilty about that one cupcake but, I am confident that this will be a MINOR setback and I am motivated to continue on my journey.
