Yes. Totally. You Couldn't understand what this feels like unless you have this.
I've been diabetic since aged 1. It's a spectrum, I've met people to whom it doesn't affect their life very much but mine is absolutely horrific.
Mine is very brittle, patternless and very difficult to control. I have all the latest technology and see the latest doctors in London and have been a patient for a worldwide doctors to examine me because apparently I'm so difficult to control and they've basically said they don't know what to do with me!! 
I don't know why mine is so difficult to control- is the first thing I think of when I wake up before even open my eyes. I have to monitor it many many times during the day: it does this, it does that, then it does something else.
it's 24 hours a day, 365 days a year. Relentless. never ever get a break. it's it's really awful and sometimes I wish I often just ......
Go away. I want it to stop. I want to have to stop thinking about it. I can't stand it. it's so intrusive, it dominates my life.
it's just absolutely awful. DH is so good about it. my two boys don't seem to mind, but it's a really awful disease and I don't think people understand that.
sometimes when I go to clinic and see one of the doctors I feel like screaming at him you 'haven't got a clue'.
I have cried about it many times over the years years and I think it's a very difficult thing.
so yes op there are many of us who do totally understand.
