Hi @ThisShitsBananas ,
I have not read the full thread so I am sorry if I am repeating what other posters have said.
I am a Type 1 and have been since I was 4 (I am now 47.) I am lucky enough not to have had many severe issues (I can count them on one hand) and have no complications as yet. However, while I am more sensible now, when I was a teen I didn't care as much. It was a lot easier to lie re testing in those days (if you licked the strip it gave a reading between 4 and 5!) and I always used to think that, in the future that seemed so crazily far away at 15, if I had issues with myself I'd commit suicide. This is obviously ridiculous, and I wasn't depressed I just didn't want to have to juggle the diabetic thing all the time or risk consequences. None of my friends did, so why me!
Now there is a lot more technology, and while the Libre is good in theory it's also, in my experience, not very reliable. I do occasionally get upset when I am NOT hungry but still have to eat, things like losing weight is far more complicated with Type 1, and even though it's more relevant to Type 2 than one, there is a stigma with 'being diabetic.'
I fully agree that your husband needs to step up and sort himself out, but I can also imagine how pissed off he is to be lumbered with this crappy condition (I can't bring myself to say 'disease'!) that has to be managed 24/7. In my lower moments, which aren't very often, I think how amazing it must be to just go to bed, or pop out without having to test or take supplies. Go abroad spontaneously without having to take medication, back up medication, and info on the bloody medication along with extra insurance. If I get an infection, or even when I got frozen shoulder, I am told 'well, you are diabetic so these things are worse' - and it really does grind you down. I need to lose weight (lockdown weight!) and it's so much harder. Going for a run is great, but I need to get my sugar up first so adds both calories and complications - it's like that with everything.
What I am trying to say is, and you probably know this anyway, is that it's easier to not care or pretend you don't, than it is to seriously manage a condition that effects every single thing you do. (I remember when I had a pump for a while being told that 'you can take it off during intimate moments, but not for more than an hour'. I laughed at the time, but it actually made me feel as sexy as a bowl of rotting fruit.)
I don't know what the solution might be other than counselling, but I suspect that is few and far between. Maybe it would even kick him up the arse if something did happen that was so serious that it jolted him into trying to sort it out? I don't know but I hope he, and you, manage to get over this sooner rather than later! x
