"...and I got type 1 when I was 23 and about to graduate from college."
Is that when you started to show signs of diabetes (feeling hot, vision getting worse, etc), or simply when the doctors diagnosed your problem? My wife--well, girlfriend at the time--was showing signs for several years before a doctor figured out what was going on. She was 16 when they finally diagnosed it as type 1.
When she explains to people that she's diabetic, the standard response is frequently along the lines of "but you're skinny!". A lot of people seem to confuse the different types of this disease.
