In the workplace, I was once the subject of "joking" like this - and it hurt deeply. But what I did was to let others know when I was making progress. I would mention things in a playful way such as "You don't want to see me anrgy! Remember, Mick doesn't like it when we are angry!" And even one alter who had to work a whole day for us when we were doing serious trauma healing shook hands with a couple of co-workers and my manager and introduced herself to them as an alter who helps me! I am able to stay co-conscious for the most part but I was so exhausted I could not step forward and stop her from saying it. They were a bit bewildered. But they saw it was very real and just a part of who I am. And when we have good days, I will often tell them "thank you" for being a friend and helping me when I need a friend the most - even if they have not been there much. It makes them a part of the solution rather than them seeing themselves as a part of "my" problem. Plus, I think they kinda felt a little bad for joking around anyway like that.

Since that time, they have moved on to joking about some other person in the office. I stay out of it as much as I can. But it shows me that even adults can be very childish at times. And they do feel bad for joking about the other guy. So I think they might actually have felt bad about joking about me. Just some ideas.
