PTSD from breast cancer and really horrible medical unprofessionals?

I have mentioned here and there the awful, and I do mean awful time I have had with drs since my cancer diagnoses. Some were cancer were related, one was a neurologist. When my oophrectomy was cancelled the afternoon before surgery, I went bullistic. The surgical technician had gotten paperwork I was supposed to sign 31 days before the surgery, had not read it all and from what she did read, thought it did not pertain to me, so insurance called and informed the surgeon's office they would not be paying for my surgery. I complained, and complained, and I said I was tired of complaining to one dept then the other, etc. I said I wanted ONE person to handle all my concerns. She said she would get back to me, that was APril 29 and I have yet to hear from anyone. I think she was told not to contact me for fear of a lawsuit (one neurologist FORGOT to give the test results she got while I was in surgery for a BMX w/ SNB and AND that I have a dangerous blood clotting disorder...I got them two months later when my FAMILY dr. looked at her tests and found it, send her an email...the nurse later called and told me she had the results but thought she would wait until I was recovered sufficiently to give me the news...duhhh... I asked my surgeon if this was info she would have thought necessary at time of surgery and she of course said , yes). THere is sooo much more screw ups this clinic had with me.I went to another clinic to see an ob-gyn for ooprhectomy. while explaining my cancer, she got uppity, and bithcy, and stood up in my face kind of thing and told me DCIS was NOT cancer, it was precnacer, well, i went off.I told her the facts about DCIS, that is preinvasive, not precancer. that she needs to get reducated, that her director of the oncology dept and the ACS deems it cancer and if that was her attitude towards my cancer she is fired and I refuse to let her doing any work on me.
So much has happened since seven months ago!! Treatments changed, drs. changed. surgeries changed, I have changed... but i seem to have nasty flashbacks, extreme fear of medical drs, nurses, etc other than my family doc and two pain drs and two of the nurses their. I push back all feelins of severe anxiety because I cant bear to think of it and relive it.I already have severe anxiety and bipolar with severe depression unrelated to cancer. Can you get PTSD from breast cancer and really horrible, I mean really really horrible drs??? I have to take xanax when I go to meet new drs now and avoid getting some health issues taken care of because I can not handle seeing new docs. When I saw my pain drs for the first time, my top blood pressure was 199!!! after laying down after my treatment, it was 136 on top.
I still have undiagnosed brain lesions they found in 2007 (which no one told me about till an ER dr found it and told me, and no one really cared). They were still present in 2010, but the neurologist that was supposed to be helping me was fired (see above). I am too scared and totally overwhelmed. I have my weekly pain dr appts, my dreaded occupational therapy apts twice a week (I dont like the one gals personality, but she does good physically for me).
What do I do???
I had to take a xanax to even write this out, my breathing is hard, my mind is racing, its an awful awful feeling.
Please help...
