Firstly, kudos to you for committing to change your lifestyle - it's downright hard work but you're already reaping the benefits so you know the good it's doing and hopefully that will inspire you to achieve even more.

As far as your doctor goes, they sound downright unprofessional. It never ceases to amaze me how those who have so little people skills or even a professional attitude - end up in that kind of role. I don't buy the whole work bearing down on them sort of thing, at the end of the day there's always a way out when you have that sort of education. If they're not happy it's their responsibility to do something else, not take it out on patients. Nevertheless i wouldn't let their attitude discourage you, maybe a firmer hand would set things straight next time. If you continue to feel unhappy with their care though have you considered a replacement etc?

I'm more than aware of what it's like to be on the receiving end of a not so pleasant doctor. I loathe hospital visits these days. There's only so much control we have so i can only suggest you change what you can and learn to accept what you can't. Often a good approach. All the best.
