I was going to comment about not being able to absorb more than 25 - 35 grams of protein at one time, but catwoman beat me to it.
I would say the best thing now is for you to rest a lot so you can heal. Try to ease your anxiety and just relax and allow your body to heal. Walk when you can, inside and/or outside, but also rest and just track your protein and water. The first two weeks, I drove to a lot of places and just walked. Like Costco, the mall, etc. I live in an extremely hot environment and sweating when I'm trying to get every drop of fluid in is counterproductive, imo. Then after two weeks I went back to the gym for cardio only, then at six weeks I was okayed for resistance training.
I recovered alone. I did fine. Family would stop by or come help when I asked them to, but they didn't hover at all. I used a binder for about ten days to minimize discomfort when I got up, walked or slept. Learn the log roll technique to help get out of bed, so you don't need assistance. If your family is driving you crazy, send them home. You need a calm environment to recover in. Call them for help if you do need them but let them know when you want to be alone again.
Just follow your teams recommendations and take your families advice with a grain of salt. Your team specializes in bariatrics for good reason. As you said, your family have never been obese, or had bariatric surgery, so what do they know? :x
