This has happened to me too. I was just getting over the covid panic when I fell and now am a bit immobile. Several of my friends have likewise been incapacitated so there is not the incentive to visit them. My younger cousin who is 60 has not been out at all and has refused her jabs.
My health visitor has invited me to a 'falls prevention' keep fit class so I hope this will help me get out again.
Anger management!!! Help needed.
