I'm not really sure what I want here and it's a bit rambling but any advice gratefully received!
I have been a single parent for about 12 years and my two boys are now both in their early 20s. DS1 is just finishing Uni so has been living away from home for 3 years. DS2 is working but often stays overnight with his GF, sometimes for weekends (she is at Uni). My parents are both long dead and the only other family is a brother at the other end of the country but we have a (friendly enough) birthday and Xmas cards type of relationship.
I do sports and exercise most evenings and weekend mornings so its not that I don't see other people or have friends but when DS2 is away I seem to really struggle with being on my own on weekend afternoons and in the evenings. I'm not afraid or anything, its more boredom and just...loneliness?
I feel like I should be getting on with jobs around the house, or going to art galleries or the cinema or doing worthwhile things that I'm sure most people with families and busy lives would love to have the time to do, but I end up doing nothing. I fart about reading the paper, looking at cat videos and, annoyingly, eating crap. I sometimes plan activities but when it comes to it I feel too tired or skint or the weather is shit and I just want to stay indoors. I can't even get interested in whats on the telly.
I'm aware that in a couple of years the lads will have moved out permanently, which is a good thing as I absolutely want them to go and make their own lives, but I am dreading the thought of being totally alone.
How can I turn this into a positive thing?
