Hi. What are your interests? Is there something you have ever wanted to learn how to do? Learn a language or study history - there is online learning. Wood working, knitting, painting, bird watching, and so on. I don't have any hobbies I engage in at the moment but I find doing anything that keeps my hands busy and my mind somewhat engaged helps. You are limited only slightly by not driving. Most everything is available or can come to you via the internet. Good luck and have fun.
