I've always been very vocal about my diabetes, especially to co-workers. For the most part they've all be very open and understanding. I recall one time I threw a hissy fit at my boss. Completely blew my top. Turned out I was very low at the moment and really had my emotions running amok. I called him immediately when I figured out what was going on, and he rushed to me to help me get my BG back to normal. I'm still amazed at his understanding and help.
I've found that diabetes is not a thing to hide. Sure you'll run into a few folks that don't handle it well. But that's OK, because it's on them to cope with their own personal issues, not you. I've also never used my diabetes as an excuse. And everyone who knows me well, knows that I don't stop anything within reason for my diabetes.
I often answer lots of questions about my diabetes. I love answering them. I also talk about what they should watch out for, and why. Like big emotion swings, or stumbling/fidgiting and ask me how I'm doing. I've also run into an employeer that didn't work with me and my diabetes. Found a new job quickly. There's just no time in life to deal with folks like that.
Good luck on your control issues. I've been through times with low BG unawareness and it's no fun. Work on the control a bit, and talk to your doc about why this might be occuring. Once you get back closer to norm, you will re-gain the ability to notice low BG.
