Dropped like a bad habit

Today I received a letter from my primary care doctor releasing me as a patient. He said he is giving me 30 days notice to find a new doctor during which time he will only be available for emergency purposes. Now me, I liked this doctor, he's straightforward, I like that.
I called his nurse she said she was out last week so she had no idea but if I would hold on she would check. She said "Dr. Estupinan received the notes from the neurologist, Dr. Cuervo, and made the decision himself. He can do that if he feels the relationship has crossed the line." I have no idea what that means. Makes it sound like I hit on him or attacked him. I haven't seen him since I saw the neurologist. The nurse further advised I should call Dr.Cuervo's office to get a copy of the notes from the visit. I called Joy at Dr. Cuervo's office, by the way she is the sweetest lady ever. She is mailing me the report.
Maybe once Dr Cuervo said it's not neuropathy, and Dr Miller had already said it's (the inflammation and pain in my hands) isn't the problem that he didn't know where to go next. I know I have to go to the hand specialist and have my carpal tunnel operated on, but I have to wait till we have full insurance in August. I think it may come across some that I don't care about my health or whatever but with this limited insurance plan and our finances there are limits to what I am able to do until August.
Just frustrated and confused kind of day!
