Struggling to Get the Medication I Need for Chronic Pain and Insomnia

How do you get your doctor to prescribe the meds you need without them thinking you're drug seeking?? I have chronic menstrual pain to the point where I can't walk and barely breathe. I've given myself 2nd degree burns with a hot water bottle trying to get rid of the pain. I let them open me up to see if they could find a cause (they didn't), and they still won't prescribe me either Norco or Tylenol 3- both of which work. I can't use nsaids. I've cooperated with everything they have suggested! On the same note, I suffer from a form of insomnia where I wake up every two hours no matter what I take (zzquil, melatonin, sleeping pills, etc). I've signed up for a sleep study and I've done everything I can to help me stay asleep. The only thing that's worked is Ambien, and they won't give me any of that either. They want me to see a psychologist. I'm not a drug seeker. I don't drink, smoke, or do drugs. I just want help and I don't know what to do!
