Is this really RA?

Hi, I am a 54 year old woman, for the last 2 years I have been telling my PCP that I have terrible pain in my ankles that unables me to walk, that my right thumb is crooked and hurts all the time (he told me it doesn't look that crooked) and I am tired all the time, that my hands are swollen in the morning. He kept telling me that I am depressed, told him I am not depressed, finally after all this time I made a big enough stink that he ordered different blood work. My RA factor came back positive. He sent me to a RA specialist. She did more blood work, ANA came back positive, low vitamin D, CCP negative. She gave me tramadol 50mg for pain, I took one and it put me to sleep for 3 hours, not doing that again, also Plaquenil 200 mg 2x's a day, after the 2nd day on that I collasped twice stopped taking it, 50,000 units of Vitamin D once a week. I have been having chest pain now for a couple of months, going to sound silly but I can't wear a bra for more than 2 hours because the pain is unbearable. History: Heart Attack 6 years ago, little muscle damage on meds. When the chest pain started the first place I went was to my cardiologist and he did my nuclear stress test 6 monts early and it came back normal. The pain in my chest scares me so much that I am taking Xanax 3 x's a day to keep me calm. Is this really RA, I have read that my CCP should have come back positive. Any advice would be greatly appreciated.

thank you
