Flea, I can't offer any advice but after reading your post I just wanted to send you a hug and tell you to stay strong! It sounds like have made up your mind to NOT let these Dr's get the better of you. I've always been the same as you... I cry when I get angry or frustrated and I've always hated myself for it. But, once I got it in my head that they are NOT any better, smarter or wiser than me, I was able to finally start getting angry rather than sit there blubbering. I think you just have to finally reach a point where you get so frustrated by all of the BS that you start getting really MAD, which for me was a good thing.
Stay strong and hang in there and as they say, next time he makes you want to cry... picture him naked!
