Early Pre-op Jitters

I finally got my date set for 12/29- I'm really excited, but also starting to get a little nervous. Not so much about the surgery, but other things:

I'm getting my cpap switched to a bipap and still need to get the right configuration and approval to my surgeon, which will take some time to figure out; then there's the fact that Covid is resurging (though still low in my state) and concerns about hospital stay during peak flu season and need to quarantine from my parents after. Then there's care for my special needs 6 year old- my parents are going to take him while I'm in hospital and for a few days after so I can rest initially, but I have further quarantine concerns regarding him too! (Me not being able to fully quarantine from him rather.) Then there's the fact that my nutritionist commented that since I've been losing about 7lbs. a month on my own, that I might lose too much to get approved by my insurance since my only comorbidity is sleep apnea- THAT really derailed my weight loss for the month, only 1lb. thus far and I weigh in on Tuesday. My BMI is still over 40, so I don't think I have to worry about that, but UGH! I've been talking to my therapist about my subconscious fear of success too. I'm just trying hard not to freak out and hope everything will work out ok.
