Hi Tom: I am so sorry you are having a hard time. My suggestion: do at least one productive thing per day, no matter what...even if it is doing a household chore or taking a walk around the block. Keeping busy, learning new things, and staying socially connected are ways to offset anxiety. Social connection is integral. And, one way to cultivate social connections is to take an in-person class or to join a zoom support group. I have recently enrolled in an emeritus college class (free!) which will offer me the opportunity to make friends with like minded people while stimulating my brain. Getting older is definitely scary. I say throw caution to the wind and "go for it!" The first step is always the hardest. Find things that spark your curiosity and will bring you joy. Get involved. Once you get started, you will be looking forward to whatever it is you've chosen. Just my 2 cents!
