Oh my goodness I can completely relate to your feelings. They were identical to mine up until 2 weeks ago.
I was just sleeved on this past Wednesday and I feel amazing. Sore, yes, but mentally I finally feel free of my cravings and good obsession. Literally it's like food, cravings, and guilt were this massive weight on my shoulders. Now? Completely different. I'm not hungry. I have no cravings. I don't particularly mind that I can only drink Protein shakes, broth, and sugar free Jello. Food has turned into something I merely need to work into my day. Not the focus of my day.
It is super early for me but I now am 100% sure this was the tool I needed to overcome my obesity. I'm sure it will get more difficult to resist my favorites but by then I know I'll have enough positive momentum to keep on heading in the right direction.
And can I tell you how amazing it is to get on the scale and always see a slightly lower number? I've never had that! I'm still bloated and constipated from surgery (sorry for the TMI) but I have already lost 10 pounds from my pre-op diet to now.
It's so scary, yes, but it will change your life. Just prepare for a tough pre-op diet which is horrible for the first few days. By day 5 of the diet I could already see that my cravings were going. It was like the diet started to reset my mentality and surgery finished it.
Good luck!
