Struggling with Sleep Issues and Seeking a Diagnosis

So it won't let me select the narcolepsy without cataplexy, but here it goes. I've had a lot of sleeping issues for years. They thought I had sleep apnea a few years ago, and now it's looking like I don't. I've had sleep paralysis 2 times in one month, leading my psychiatrist to think it's not just my medicine, making me tired. He thinks I could have narcolepsy. I'm due to see a sleep doctor in a few weeks now (been waiting over a month or two so far). From the brief conversation I accidentally sent to her, she thinks it's me just not using my cpap right. Which I don't agree with, I feel like I'm in compliance. I'm not sure how to get her to take me seriously and how to get her to think it might be narcolepsy (minus cataplexy). I have a lot of the symptoms, and even my psychiatrist (who willingly admitted he's not a sleep expert) and therapist think this could be it after ruling things out. I hate that doctors never seem to take me seriously! I just want to know what's going on, and hopefully be able to treat it. I don't think that's too much to ask. This NP just seems very flippant about my problem
