Very nicely written, Jen. I, too, struggle with the decision to disclose the fact that I am somewhat handicap. Due to three strokes, I have somewhat less strength on my right side than my left. Diabetes factors into it as well.
I have found that not mentioning much at interview, and trying to be as normal as possible works best for me. When asked, I talk about my issues, but don't push it or bring it up. My pump is at my side, but I bet not too many of my co-workers know what it is or how it benefits me. As you do, I always turn off the alarms when in one on one situations, church or singing in concert.
I think your observations and actions are spot on!
