im trying to figure out what I need to do regarding abuse from my doctor.

I have seen my doctor for about 10 yrs off and on as my primary care doctor. the last year or so I have suffered from severe bouts of Depression and as well as some very painful physical issues that I been under his care for.

about 6 months ago, I was going thru about the darkest time of my life and was close to being suicidal. my show a lot of personal kindness at first during this time as he knew I was also very alone. he began to befriend me and told me that he would meet me somewhere for coffee if I needed to talk and couldn't afford the visit. he also offered to pay for some procedures that I needed and couldn't afford as a friend to me that wanted to help. he would call to check on me because I had been so severely depressed and find me crying and asked me to come to talk to him. soon he became the only person I had to talk to honestly and could tell him anything, but he was also comforting and pay a lot of attention as well as paid a lot of compliments etc etc. he was also totally aware of my history and the depth of the emotional state I was in as well as were I was vulnerable. he finally told me that he wanted to spend time with me and talk and help me feel better , dealing with things again as well as a part time sexua| relationship and that he was married for 20 years and they were somewhat estranged.
of course I had begun to really depend on him being there for me. I told him that our relationship friendship was the most important thing for me and that it was the only reason I had been able to hang on and keep going and pull out of Depression and got better, and that I knew he had a different place for me than I did for him because I needed his emotional support and asked him to promise me that he would always put that first and not do anything to damage itif we took it to the next level, because I needed that support very much still. he was also aware I had huge abandomenbt issues. to make a long story short once I agree to go to that level, he changed immediately after that and became alof, vague, distant, got upset because I talked about the problems I was having instead of phone sex or just sex in general. he stopped caring how I was doing on meds and started playing very cruel and sick emotional games with me and would laugh at me about all lies he was telling me and then doing opposite of things he said he would do. he would make fun of me because he knew he was humiliating me and when I would say something about it he would blame me for all of it or he would say things to me that I expected and then turn it all around that he didn't.he would pull me in and then get a kick out of emotionaly abonding me everytime and laughing about it. I could go on and on but you get the jest. I hold told him several time I couldn't be involved anymore because of the games and abuse but he would keep calling and saying how I misunderstood it all blah blah blah and that he would do better and how much he cared. but each time was worse and effected me so negetivly and I started back into horrible Depression feeling so worthless humiliated and betrayed. I was near that suicidal point again and told him that. once again he did the same things and for the most part I didn't know if I was coming or going with it, it was so cofusing and devastating for me!!!!!! and them to know it was all a big joke for him to see me suffer and be confused and pursue him to understand!!!!the other day something very curel had happened and I got very upset. I said that he was playing games and didn't care about how it affected me at all and that he thought I didn't matter so it was ok and that he screwed up. he commented to me .... I know I did!!! so he knew exacty what he was doing to me the entire time!!!!!!!!!!! he knew my emotionaly state and had gained my trust and then completely betrayed me!!!!! I am so devasted by this right now, I don't even know what to do!! he shouldn't be able to just get away with doing this and im sure im not the first!!!!!!! what should I do!!!!!!
