MaggieTulliver To manage health concerns, I largely ignore them, Covid situation means shelving them anyway and I cope with being older (73) by doing exactly as I want! So try and really enjoy yourself, doing the things you love.
A friend once told me to take the word ‘should’ out of my vocabulary, so apart from the things I can’t get out of, I’m a hedonist! (When Covid allows me...)
If you have lost your faith, which I assume you mean organised religion, you are probably spiritual in some way, most people are. You can have a faith in humanity, your children’s lives, if you have them etc.
Classical music brings out my spirituality.
