I'll raise a toast tonight, but I'm out of whiskey, so it may be gin.
For me, part of my "comfort" was knowing I didn't have a kid, a spouse, or a house, or a pet, or even a house plant. I had nothing to do but focus on my recovery. My insurance was good, my car was paid off, so my only monthly expense was my apartment, which I held on to. I didn't feel like I had let anyone down by not being able to support them (in a financial sense). Instead of being too busy to be discontent, I was free to absorb the experience of my recovery and focus on every minute detail as it changed. I chalked up every "victory" I could, no matter how small, and I was motivated by seeing the list grow. I also had a good support group of friends and an amazing mom. She happened to be retired so she had the time to be with me daily and help with things like state disability paperwork.
Sounds like you have a good wife, and kids old enough to help in many ways. It also helps to have a job that doesn't require physical labor. I'm in finance, so having a desk job has been good. It would be much tougher if you had been a construction worker.
Congrats on the stomach sleeping. I still can't do that. I can, but I'd wake every hour to pee, or go through a ton of diapers and laundry. Good luck with the sores, they are frightening.
