A lot of good suggestions have been offered and many work well. Having been a business woman from the age of 20, in retirement I found I needed a purpose in life in addition to enjoying finally being retired @ 65. I live by myself with 2 precious kitties who light up my life every day. Pets are wonderful mood boosters. Early in my retirement I submitted an application to join the Senior Advisory Board @ my local city. They plan activities for the city's seniors (most are free), have fairs during the year, day trips, dances, hobby & exercise classes, Bingo, movies, a book club, lunches, etc. I was so happy that I was successful in being appointed to the Board and served on it for 16 yrs. In doing something that enlivens other seniors' lives made mine even better! I would encourage seniors to visit their city's senior centers or those of other cities nearby and make new friends & attend events & games. I've been told by many of our seniors that they have made wonderful friendships at the center and support has always been there when life problems happen. One lady I am friends with recently lost her husband and was getting very depressed but was not leaving her home. I encouraged her to return to the senior center where she had friends & she did. She's doing much better now. Over the years I've made many good friends who are a big part of my life. Hope you'll look into a senior center at a city near you. If you don't drive, most have bus service to and from the center.
