I SO understand the aging thing right now. At 69, I feel like my purpose in life is garnering a paycheck. Was getting really depressed and then started volunteering at our little local food bank. BEST thing I have done is quite some time. Despite the fact that my work schedule right now does not allow me to be consistent, doing for others, ESPECIALLY during this pandemic has helped ME far more than helping those in need. I got switched to graveyard at work so not able to participate right now, but know it is a temporary situation and check in with those that are on those front lines, so still feel "attached" to it and know it will not be too long (God willing) before my schedule changes back) and I can get back to it. I did not expect it to affect me as much as it did. Don't know if you can find a volunteer position to try , but it really helped me. good luck and I so get how this aging thing can screw with our heads and hearts.
