I have just realised (after decades of living alone) that I am actually desperately lonely. I am single, live alone, have some friends but they are all busy with their families. I am a teacher and I get all the interaction I need in term time and am too exhausted to do anything after work or at the weekends. But then it comes to the holidays and I just feel so alone. I feel like my life is very unbalanced and I don’t really know how to fix it. Does anyone have any advice?
