Melinda, I know exactly how you feel and I empathize with you. Understanding this disease is one thing: anyone can read up on it, attend seminars, participate in fundraising activities, etc. However, and the term that Richard used is bang on, not everyone can "relate" or appreciate exactly what we go through. A lot of people think that Type 1 diabetes is just about the needles and finger-pricks. If it was just that, and I could live my life completely freely without worrying about anything else, it would be easy! But, we all know it's not that way... there's so much more to this.
Dealing with high and low BGs is, of course, one of the added difficulties. But then there is also worrying about long-term complications... And, the motional side of it is a whole other story too! I still, at my advanced age (41), still have crying fits every once in a while, especially (excuse me, gentlemen!) at certain "times of the month" when I am feeling more emotionally vulnerable. But I don't see anything wrong with that, mostly because I also don't tend to dwell on the negative aspects.
I recently got super excited, like a kid at Christmas time, about trying some new infusion sets. I seriously could not stop talking about it for days! Just like your husband, mine finally looked at me and said "I'm really sorry, I can't listen to you about this anymore". I was slightly hurt, but at the same time, I could understand; again, it goes back to him not being able to relate to my level of excitement.
I guess an analogy can me made to a few years ago, before I started getting "into" NFL football, and really knew nothing about the game, let alone the teams, I would listen to him going on about such and such playing, rushing so many yards, interceptions, 2 point conversions... all Greek to me at the time! Would the boredom eventually show in my face, as I was hearing but not necessarily listening to his banter? Of course! Since I started getting interested in the game, I have learned a lot, by watching, listening and reading about it, but he still cannot get into the details too much, or I lose interest because I can't quite comprehend. It's not that I don't "care" about my husband and his interests, but I just can't always "relate". Make sense?
As others have already stated, I also rely quite a bit on the support I get through Juvenation, as well as through Facebook, where I have also hooked up with a good number of diabetic friends. Hang in there Melinda and know that there are a lot of people who understand, but also A LOT who understand and can relate!
