Mei Mei ~
I'm sorry to learn of the outrageously insensitive treatment you received at your therapists facility. You're right: no excuse for that kind of abuse of a paying patient with pain issues. Your note to his office was pretty much what I might have written in your situation; factual, civil but clearly indicating your anger born of frustration. In my never-to-be-humble opinion, you did the right thing. I hope you feel better by now and can find a more caring practitioner. I sympathize with your disappointment in Michael and other people supposedly in the 'caring' business, with their emphasis apparently more on the business than the caring. I commend you for, like Diogenes, seeking an honest (caring) physician/therapist. I truly hope and will pray that quest is ultimately successful. You deserve to find physical and emotional respite.
