I'd have lost it. Kudos to you that you didn't! I don't take mockings like that lightly due to the obvious..........living with type 1 every single day with no off days. Before they could even get there, I tell them "wanna be a tough guy? here's my pen, let's shoot up a couple of units to see and feel my life from your own perspective, but I warn you, insulin may kill you and make it one of the most miserable ways to die. You'll start sweating, your heart will beat out of your chest, you will feel a kind of terror that you've never felt before: the most obvious feeling that you will die without intervention. That's how I feel often times. Be a man and try it.". They quickly shut up, and start treating me with respect. You have to put them in their place before they could even go there. I also feel that it's important to have your coworkers know that you have this condition, so that they know how to treat it in case an emergency situation arises. I'd feel uncomfortable being around people on a daily basis who are unaware of my condition and/or belittle my medical condition, but that is me.
