I am an open book, need help to lose weight quick....

I am sure I will probably get hammered for posting this but I need some more suggestions. I am trying to have an outpatient surgery but need to lose 35lbs before I can even think about it. I am currently using IF with no real results but I have only been doing this for 3 weeks. I have tried 1200 calories a day, 2000 calories a day, I have been to my doctor, a nutritionist/dietician. I am currently weight lifting 3 times a week and work out hard cardio 3 times a week. I wear a heart rate monitor so I am not just using MFP's calculations on calories burned. I want to point out that besides IF the things I have tried have been at least 6 weeks. I try to log everyday but sometimes the weekends get a way from me. I hardly ever go out to eat and I try to eat as healthy as possible. I am just so frustrated it doesnt make sense. The nutritionist said if I was a little heavier I would be a good candidate for bariatric surgery!!!! That is NOT what I am going to do, not that I have anything against it but it is NOT for me. I am open for suggestions just please do not be mean lol.
