Hi Sadiesnan,
I really get you. I too am a very private person and have very few friends. I was a professional woman in my working life and like you, had a good education. Time can hang very heavily and it can be very lonely. My son's wife will not let my grandchildren come to see me because I have a dog so I don't see them or my son except for once a year obligatory Christmas visit, minus the dog of course. I too have looked at joining the U3A but am put off by it's structure. I am not sure about learning much from an amateur expert. Being old fashioned, I still prefer tutorial type learning. I do get in the garden when I can but having rotten arthritis, I am restricted a lot.
I do have a husband who has just retired, but although we are very close, he prefers to live his life independently mostly during the day.
I seem to have come to my own routine. I watch the TV news until 9.00am, and then get dressed etc. My next job is to check my computer and this can take up some time. Then I try to find a small outing to go on, the garden centre, my local village, and one day a week I visit a very elderly lady close by. Although she repeats her stories endlessly, I always enjoy seeing her and I know that she feels perked up by the time that I leave.
Do you live anywhere near me? I live in a small Derbyshire village. We could perhaps meet up some time? Alternatively, how about an email based chat on a fairly regular basis? That might be interesting?
Anyway, I have chatted enough. See how you feel and whatever you decide, I wish you well.
Cheers for now.
