1. Own your mistake.
2. Forgive yourself.
3. Get back on the wagon. If you have to, go back to your pre-op diet for 2 weeks and then work yourself through the entire process again.
You have to motivate yourself and learn to depend upon yourself. People are going to let your down and people can't be there for you 24/7. As long as you become your own rock then you will naturally attract and be attracted to the right people to share this journey with.
