How do you all deal with the mental aspect of all this?

How do you all deal with the mental aspect of all this? I went from being a super active person, at 47 years old I could run circles around the younger girls at my job (waitress). Loved to take long walks, which was my main coping skill for anxiety. I was totally self-sufficient. Now, living alone and I can't do anything. My parents, who are old themselves, have to help me and even driving hurts my feet. I am feeling so isolated,
