I do have my hobby things as well, and know what you mean about being alone at night.....I fall alseep with a video usually.
BUT I have found one place where all the other lonely people go, and even though I go by myself, I never feel alone there......and thins is gonna sound funny, but it is Karaokee....lol. People there bond silently while toghether, weather silently on the sidelines, or up on stage. It truly is a place I never feel alone, when alone.....I go swimming and take my toddler to play groups etc and still feel as alone as can be at those activities, but at Karaoke, we are all there, mostly alone, but together. :)
