Diabetes burnout

My doctor just signed me off for a sick leave due to diabetes burnout. I feel so ashamed and upset how my sick leave affecting my colleagues as currently everyone on sick leave due to flu. And I am going on sick without any flu. I had let some things slide in my diabetes in the last weeks or maybe months because was a lot going on we were moving house to newly build place and lot was going on at work. I didn't think my diabetes management was so bad but it wasn't ideal for sure (e.g there were multiple days I was forgetting to eat whole day and going low or was snacking something without realising but forgetting to bolus). I recognised it when I needed to extract pump and CGM graphs and I worked hard to correct it last few days, though of course it was too late, but i was afraid to be judged due to how bad it was. My diabetes management was ideal for many years. Before appointment I needed to email the graphs to my doctor and my doctor seen straight away where the problem was and that i wasnt doing good job some of the last weeks. I told, that yes I let the things slide, there was a lot going on and I am working on it, but the doctor insisted I get sick leave to put myself together and focus solely on my diabetes, weighting my food, counting carbs and they will see me at the end of it in 2 weeks to check the progress and then again in 1 week ( normally I am seen every 6 months and the rest of the time its just other medical staff, e.g nurses for blood test). My doctor also written multiple books, research papers, training for other doctors in diabetes, so they probably right, but I really didn't think it was so bad. I thought I had few unfortunate weeks but I was still managing it. My partner is now upset too, as he thinks it his fault he didn't realise I wasn't coping. And perhaps it's me who is in denial, thinking I was coping and still could get back from it on my own when I wasn't. Just did anyone had it and how did you cope with diabetes burnout? Also how to stop feeling guilty for letting my colleagues down being sick. I feel I am not really sick, like I am just slacking or got the holidays to care for my diabetes. Maybe I indeed don't recognise yet I have a problem.
