Hi and welcome!
About the breathing tube: I was worried about waking up with it in place, but when I woke up the only tube I had was a urinary catheter. Well, of course I had an IV. In my case, however, weeks down the line I discovered I had an overgrowth of scar tissue in my vocal cords--a reaction to some sort of injury from intubation. The good news is that the surgical repair to my vocal cords was "outpatient" with instant relief from my throat symptoms. And I really know no one else on this list who had as much throat damage as I sustained.
About being alone. Despite having a grown daughter in a nearby suburb, I was alone. (My daughter had a new baby and her husband was opposed to having me stay with them for 2 weeks. I chose not to fight them.) I had a friend drive me to the hospital on the day of my OHS and, because she needed to get to work, just drop me off at the Hospital door. I walked myself up the the surgical area. My clothes were an issue because no one was available to "take" them away after I went into surgery. Then the clothes remained lost for a few days, but, I was told they were found in an operating room. I have a hard time visualizing that one!
I was visited as a OHS patient post-op, and my daughter and husband did pick me up on the day I was discharged, but I almost had nowhere to go (since I was told I could not be "home alone" for 2 weeks). I started calling friends and acquaintances begging for someone to take me in. Eventually some acquaintances from my church took me in and it was a wonderful 2 weeks! Then I was allowed to be home alone.
Once home, you will need some elevated toilet seats and easy access to food. I used my microwave to cook the frozen dinners my daughter had helped me stock up on. Also, I needed a ride to my INR PT anticoagulant tests. Again, I got out my address book and called and called until I found a person who was delighted to drive me.
Living alone does not mean you cannot get help if you ask for it! I am now good friends with the people from my church who took me in at the last moment. I remember my time with them very fondly!
