I agree with Calgalintx, I also work in a hospital and talking about patients in such a way is against policy in most places. You should report her if you can or ask for a different nurse to be assigned to your care team.
Take some deep breaths, you'll recover as quickly as your body is able, try to work on easing some of that anxiety you're feeling right now. Do as much water/walking as you are able, the walking will help relieve pressure you are feeling. Request more pain meds if the pain makes you unable to walk. Sip water as slowly and as frequently as you are able so you're not trying to play catch-up when it's time for discharge. Most importantly, talk to your Dr. to let them know you are struggling.

83 lbs is GREAT!
It sounds like you and I are on similar paths. I'm at 11 months and have lost 78 lbs and I have about 40 left to lose. I contented myself with losing very slowly. Could I have been more faithful to the bariatric diet? Yes. But I'm happy and I feel great and to me, that's all that matters.
