I can really sympathise with your dilemma. I have had a similar problem once I retired. It has taken me years to learn that I can gently say no. But it has left me isolated. CC is disabled so I already have a lot of caring to do. I have some good online friendships and book club is good too. I have found a walking club for those who are more able. The rule is no talking about illness! Can you start one up yourself. Volunteers for nature monitoring usually attracts younger and younger/older men and women. My SIL does a dormouse monitoring route. And groups often go out together. Hope this helps.
The King is to resume some duties.
To go through chemo therapy or choose not to?
Have any of you got all electric cars? Pros and cons please.
