Ok, yes! Be hard on yourself. WTF? Seriously. Call your surgeon and get a referral to your RD and to the bariatric counselor. Start therapy now. This may sound harsh? But you are 4 WEEKS post op! This is the "easiest" and the "hardest" you will ever have it and the time you will feel LEAST like eating in your entire journey. Cuz barring complications like it sounds like you're asking for, your restriction will get increasingly less and less as the months go by and you continue to heal and evolve. You either take care of your food/behavior problems now? Or you could be doomed to either never see goal, or regain.
Tough? Fu*k yes. I am being tough and shocking. I hope it shocks you into getting a grip and getting real with your bad choices.
It begs to be asked...Why did you have this life-changing surgery if you weren't ready to get serious about living a new life? Ask yourself, WHAT IS YOUR WHY? WHY did you want the surgery? WHY did you want a new lease on life? How important are YOU? How important is your marriage? Your LIFE?
(Seriously one of the saddest posts I've ever read and I've read a bunch including a post-op eating pizza at 4 days.)
