Roscoe, T2 per se isn't considered a disability, and T2 is supposed to be considered, taking into account case-by-case factors which might impact on the individual's ability to perform their job. However, I would say anyone injecting insulin to control their diabetes should be afforded the required adjustments etc. HR/Equality Act isn't my area of professional expertise, but I do have a decent understanding more of the HR stuff than the specialist DDA/Equality Act stuff. Honestly, in your shoes, and certainly as an outsider, looking in, I would urge you to take this very steadily and don't rush into any decisions. When the going gets supremely tough, and we're battle-weary, it can be easier to have the odd feelings of, "they can just stuff it", and want to carry that through, even when we know that's not the "usual us" talking. What I would really hate for you would be for you to walk away and regret it once you'd had a period of respite from the pressures. I would urge you to work with your employer/HR to clarify what, if any adjustments they can agree with you to allow you to re-grasp this thing by the throat, and to get your overall mojo back. It could be that a period away from work would work well, to afford you thinking time and to work out some strategies for remembering some of the things that get overlooked when it gets hectic. I'm sure if you went to your GP complaining of diabetes burnout he would be sympathetic; especially as you say your sickness record has been exemplary. Do have a think about a couple of weeks away from work to really chillax and think about it all. I'd be trying to work out where the "hot spots" are in your working day and see if you can think of ways your employer can help ease those a bit, even if it's just for a while until you can see the half filled glass for what it is. Something you have enjoyed for many years. It's not an easy one, and who knows? Perhaps at the end of all that thinking and planning you might feel the same about retirement, but it will be a decision not reached in a time of crisis or haste, but based on consideration and calculation of what's best for you and your loved ones. If you were to retire, have you considered how you would spend your time? I sold a business and tried to give up work. I lasted a grand total of 3 months! Yes, I had successfully sold a business and put my financial security on place, I wasn't happy with the lack of direction because the sale happened very quickly and I hadn't done my personal preparation (personal referring to my personal life, outside of work). After 3 months, I found myself "a little job" and ended head hunted and hungry, back into the heat of the fire. Retirement isn't just about packing up our desks and putting the briefcase to the back of the wardrobe. It's way, way more complicated on a personal level. I do hope that doesn't come across as any form of lecture, because that's not my intent, but the written word doesn't always convey full context.
