Ladybird.....as we have discussed....there are so many factors that make it an up-hill climb for you.
And, I also get it that your current location as lovely as it is....makes the isolation worse for you....I know that you have indicated that it might be possible to move in the future.....perhaps you can keep that as your "light at t he end of the tunnel"....
I do agree with those who say to cut back on the volunteering that increased your workload...but, doesn't offer the gratifications that you had hoped that they would.....
