((((hugs))) Now you KNOW much of what you say about "just" is just not rational thought!
That the doctor became angry is HER problem. Too bad she can't deal with what you have to live with!
Maintain the status quo... yes, advocating for yourself, doing good self care is NOT easy, or everyone would be doing it!
While finding another doctor might be an option, try to work out the relationship with this one first. Now that it's come to a boil, it might simmer back down some?
Make a list of what you need and what you expect. Apologize for previous misunderstandings, explain how you are working on your triggers (and if they don't understand that is their ignorance, it can't change your course of treatment.) Try to regroup and begin again. Have an adult conversation with this information.. hopefully you both will be able to remain calm and agree to work together on it.
I tell ya ww, I sware (if I did) that my MD has TRIED to get me to leave so she wouldn't have to treat me for my pain... but I'm not budging!
