I think there is a lot of wisdom in what's been said here, but I like what George said the best. One of the things that I am beginning to learn for myself is that as long as I am willing to meet my own needs and take care of myself I trust myself, and I know that if something happens and I am let down it will be painful, yes, but I will be okay because I have learned or am learning to take care of myself.
Isolation is very painful. I've been isolating a lot lately. The outside world is too much. But today there is a thunderstorm. There's hope for me yet.
I hope you feel better soon...
