I hear you, over the past several years I have had a lot of adjustments. don't drive anymore, my lack of mobility is a constant battle. Thank Gxx I have great friends that give me rides, visit, etc.
For the most part I am house bound; I was the epitome of independence previously. This process just keeps advancing, I'm learning to accept it, but I don't like it. Another thing that helps is a 12-step program that I have been a part of for over 40 years, some components consist of mediation that I practice, fellowship and prayer. Although it is not religious it provides me with me with spiritual guidance that puts my life in the framework of one day at a time. So, I live 24 hours at a time. I don't know if all this rambling has helped in any way, but I hope you find some relief. Good Luck.
