So, I recently started group therapy for some mental health issues, and the only slot available was 4-5pm. So I need to leave work around 3:30 twice a week for this. It's not really an issue because my type of work is very flexible, and I come in to work early. However, I need to put it in my calendar so people don't schedule me into meetings at that time.
However...I don't know what to call it, or how to respond to people asking me why I have to leave. I'd use the "my kids need to be picked up" excuse, but they know I don't have kids. I'd put doctors appointment, but our calendars are public and I don't want to make an obvious lie. I also know I don't have to tell anyone, but saying "none of your business" or "it's too embarassing to say" doesn't seem appropriate.
What's the protocol here?
