I have had the same issues, been divorced for 7 years. Go to a trusted friend and make plans. Find a hobby or support group. Reading a good book, even puzzles help to keep your mind off of it. One friend of mine who is divorced volunteers for a dog shelter. It really makes her feel needed and dog love is very good. They need volunteers at many of these shelters. Another friend volunteers at assisted living facilities. Being a helpful nice person that comes to help people who may rarely see a visitor is nice. Just some ideas.
