I won't give up, I won't give in

I won't give up, I won't give in, even though I'm really struggling these last 2 weeks with my Oola life journey.  I have been very tired and not eating as good as I was.  I was doing so good and hit 20lbs. In the last 2 weeks I gained 6lbs back.  I'm so disappointed in myself.  I need a boost.  So starting Tuesday after the holiday weekend I am going to do the Lean and Burn program with Oola Teas, https://www.oolatea.com/180 .  I have been on this journey for 104 days.  I haven't gone back to coffee although I have been craving it all week.  I want to cave in but I haven't.  Looking for suggestions on motivation.
