Dealing with Chronic Nausea and Being Accused of Drug Seeking

So I have been dealing with my chronic nausea now for almost 3 years. A few months ago I was having really bad nausea with upper abdominal pain, my husband insisted that I go to the ER so I did. When the Doc came to see he he accused me of seeking drugs. This was after I explained to the nurse that I did not want narcotics because I have a history of drug abuse. I cried. I cried till they just let me leave. I will now more than likely never go to that ER again because I can't stand the idea that a doc would accuse me of just seeking drugs when I specifically said that I didn't want them. Needless to say, I feel like this is part of the reason my regular docs haven't figured out what's wrong with me.
