I've been obese most of my adult life. I get how you feel, I really do. I probably gave up on trying to do anything after years of yo-yoing the same 3 stone down and up again about 4 years ago because sustaining a "diet" for as long as I needed to felt overwhelming and impossible. Every single time it ended in a complete binge on all the wrong stuff.
This time last year my BMI was 43 and I turned 40. It wasn't until my daughter expressed concern about covid killing me that I realised I absolutely had to change something. Stupidly knowing all the other things that could kill me never bothered me...but knowing that my size was worrying my daughter was the last straw.
I started couch to 5k with a fucked up leg constructed mostly of metal and took control of my food. The control was simply giving myself a target of calories and tracking everything I ate. If I went over it wasn't a big deal, I just made sure the next day was better. Every day is day one, I try my best and that's good enough.
11 months on my BMI is 35.5, I've dropped 3 dress sizes and I can now run for 90 minutes non-stop albiet slowly compared with real runners
Your BMI is lower than mine. You haven't pushed yourself into the highest risk category which is great. This is fixable without surgery. Get in touch with your GP and ask what support they can give you to lose weight, but the crucial piece of advice I have is that this needs to be forever...just like if you did have surgery.
You need to be in control of your relationship with food, by whatever means works for you and make it part of your life. You need to accept that changing for good in a sustainable way takes a long time, but it is very worth it.
Give yourself small goals. Aim for 5% weight loss to start then see how you get on. Best of luck to you, but honestly please give being in control a good try before seriously perusing surgery
