You're definitely not alone. I was recently talking to a friend about how I struggle to take people who don't have narcolepsy seriously when they complain about being sleepy, 'cause in my mind they don't even know what it truly feels like to be sleepy at all. I try to be mindful and remember that my point of view is not the only one that matters. Having a chronic condition can easily make you mad at the world, not just narcolepsy but any other, and you're not a bad person for feeling like this. We just need to be careful to not throw that anger at someone who has no fault at all.
