I kicked a foul-mouthed bastard out of the clinic today.

4. I'm sorry to hear it

Is he an alcoholic by any chance? I'm asking because a few years ago that might have been me. I'm normally a very civil, friendly person, but alcohol turned me into a total arsehole such as you described.

I have only dim recollections of that time, but I do recall that my A1c during that time was over 12% and the doctors (emergency and otherwise) had clearly completely given up on me. I was apparently foul-mouthed and aggressive and I woke up several times in the emergency room to very cold facial expressions from the medical staff I'd apparently abused horribly after my wife called 911 the night before. I cringe at what I've been told I said and did during those times. Although some of it actually made me laugh -- apparently I'd been calling doctor Michael Smeagol, and I must admit the next day that there was a resemblance...

For the record, I'm a success story. My a1c was below 6% the other day and my pancreas, kidneys and liver and heart have returned to normal function contrary to expectations. It can be done.

I hope your patient gets the help he needs, but I suppose innate rottenness of character is incurable....
