Can you get a visiting nurse or a caretaker? Surely there are other people your age who have no one to help them when they are released from surgery, so I would imagine that it's possible to get a visiting nurse or caregiver. If not that, then rehab is an option. Lots of people go to physical rehab after surgeries.

But if you say you have no one to help you out (since you live alone, I assume), then the hospital will probably try to be accommodating by getting you a nurse or caregiver.
