Echoing everything that has been said on this thread. I find 5-8pm the hardest time of day and Sunday the loneliest day. I try to find something to do, even just walk the dog or pull weeds or organize the shed, just to have the time pass. Watching a movie kills 2 hours. I try to tell myself feeling lonely is part of being human and have myself felt lonely at times within a relationship, which in some ways was more difficult for me. A good book can provide escape. I’ve started a few that were good but then found the subject was triggering my recent relationship issues so it took awhile to find the right kind of things to read. Hang in there, you are not alone!
