I was married for 48 years and after my husband died in July 20166 I am not sure what to do with my time. Before he passed away, he developed dementia so the time leading up to his passing was very taxing because I always thought he would get better so that we could be together after I retired. Now I am retiring as of January 2017 from a job I worked at for 37 years so now I am really having problems with managing my time. My children are grown and out of the house. I am in the process of scheduling knee surgery on both knees so I really don't what my plans are going to be. Do you have any suggestions?

Sorry for your loss. Have you considered volunteering after your surgery? After 37 years, you are a wealth of knowledge. When you find ways to stay occupied you may find time management will become easier;because, now you have a reason to manage your time. It has been my experience that when I just leave my days to whatever may come. Nothing really comes and I am lost. I plan and sometimes I do a great job; then there are days I still struggle with consistency ; however, I refuse to give up! Plus, volunteering would certainly be good way to meet new people, Even better if you can find individuals that share similar interest.
Perhaps you may consider having lunch with a friend or two and find out what are some of their interest, Speak with church members,
If you love animals; perhaps the local humane society. You strike me as a planner, don't stop. And don't let time manage you, YOU MANAGE IT!

Check following out...hope it's not anything like that!
