How very sad. Unfortunately some things you shouldn't do, I was banned from driving due to my diabetes and this limits every aspect of my life permanently. At 55 I find I have an accumulation of unfortunate experiences from not getting that job to she's drunk to she suffers anxiety when really it's just the physical manifestation of hypoglycemia or hyperglycemia particularly if it's acute. Any how if you search there will be something that is perfect for you..so don't give up and remember it's not you that's failed more often its that people have failed to understand or recognise the implications of diabetes. In your case yes probably HR didn't realise the problem given that particular role or job.
