I get that you are frustrated and perhaps angry.
Honestly, it's not too late for you, unless you give up. Your surgery is still there. It will make what you still need to do easier.
From what I see you have received good advice: Follow your plan to the letter, weigh your food, log your food, don't drink with meals. These things are what will get you losing weight.
These are also the things you refuse to do.
It seems you would rather quit and blame the surgery. As with all things, it's your life, it's your choice.
Good luck,
