Getting back into the work force

About three and a half years ago I left my job to become my parents full time caregiver. They are both gone now and I am interested in either going back to part time work or do some volunteering. However, during that time I was diagnosed as a type 1 and am now insulin dependent. I am not sure how to handle telling a perspective employer that I am diabetic, so I don’t go out an actively look for opportunities. Any suggestions?

I have been T1 for 30 years. I have never told any of my employers about my personal medical history. Eventually, I do usually tell a close coworker if I feel like its something I want to share with them, but I don’t make it a rule to tell the boss. I figure as long as i’m able to show up every day and do the job, it’s nothing that they need to know.
