In process of insurance review for approval

I have never been so anxious about anything. My last visit to surgeons office I was told not to lose any more wt. Like wtf?? Isn't this the whole purpose, but before my financial counselor could respond it clicked.. Oh wait... My BMI may not qualify me. Got it.. So the struggle lately has been maintaining my weight. I've done keto diet for 30 days and lost 17 lbs. I have another 80lbs to go. I'm currently at 235 and now apparently I'm 5'4 and not 5'5 anymore. ☹️
I'm a bit nervous that the insurance will have me do these classes and then I won't qualify for the surgery. Everything else had failed for me with dieting. I don't do much exercise because I'm in tons of pain from knees and hips. Forgot to mention had a total hysterectomy and not on hormone replacement which can cause early osteoporosis. I'm only 40 and about to be a "Glamma". I need the strength and prayers. Anyone have this issue at all?
