Being a person that has had several surgeries and live with disabilities, the best advise I can tell you is you must enjoy your own company!
Now is the time to read the book you always thought that you would.
Look into a hobby that takes a lot of reading. May I suggest Ham radio? as that will require a ton of study, for most people! With a Ham radio lic you can meet people all over the world without leaving home. I like talking to people in all the countries I went to when I was in the Navy.
Grab the laptop or iPad and google any word that comes into your head! You might me surprise where that leads you.
These are a few this that I do, hope this helps!
