I am in need of understanding from my doctor about my medications

I am currently on Vicodin 7.5/325 evry 12 hr. I have been on this for about 10 months after trying all the other non narcotic meds my doc wanted me to try. He will not listen when I tell him my body has built up a tolerance to the meds. He will not even call me back himself, he has his nurse call me, and then he wants me to come in to talk to him and pay another 50.00 when I just saw him 2 wks ago and talked about the same thing. He wanted to refer me to another doc who knows more about Fibro. So at first he sends me to one that does not take insurance at all and wants 350.00. then he sends me to a Neurologist who only is interested in my sleeping and my headaches, and says she thinks I have MS, and wants me tested for Narcolepsy!! I mean Im always tried, but NEVER do I involantarily fall asleep?? So I called him agaim yest, and his nurse said he will not try a diff pain killer only a muscle relaxer which I already take but only at night due to sleepiness. So his nurse tell me he wants to send me to an accupuncturist, so I ask just find a pain center and send me there pls, and she then says if I come in and bring the rest of my Vicodin that he MIGHT give me another opiod med. So I go over there a lunch, and a sign on the door says they are closed for the day. Im being treated like an ADDICT, and Lied to by a person who is supposed to be helping me not letting me suffer in tremendous pain, due to me being a nurse and on my feet all day, walking all day, and using upper and lower body mvmt all day, at the end of my work day I dont want to do anything but laydown and not move, but then that's not fair to my 2 kids to have a mom who is in pain, and who cant play w/ them. Im all out of ideas for this doctor. I have even given him literature offline about Fibro, and opiod meds PLEASE HELP ANYONE
