Hey @jparadigm, I wanted to say I am sorry to hear that you are struggling. I do think however that these feelings are entirely normal, and from reading others who have posted in these forums, a lot of people do go through this.
Dealing with our relationship with food is one of the hardest things to do, but as you know, is a key part of working with the tool of surgery. I think your idea of maybe seeking some help from a therapist/counsellor would be a good idea. I am pre-surgery, but I have therapy every week and my main focus at the moment is around my relationship to food.
I would say however, try not to beat yourself up too much, as this can do the opposite and not motivate you at all. You're still healing, and that takes a toll on you mentally and physically. This is all new for you.
Maybe start a journal and when you are feeling those cravings, write down what it is you want, and how you are feeling in that moment - try and pinpoint exactly what feeling is driving those cravings, sit with it, be interested in it. Hopefully that may start to give you that time to acknowledge how you are feeling before any incidents of deviating from your current food plan. Then think maybe about something else you can do that will give you that hit of dopamine!
Either way, speaking to someone about how you are feeling and seeking to address your relationship with food will be key, and you have already taken that first step in admitting how you feel here and seeking help.
Be kind to yourself x
