I think I have narcolepsy

I am constantly tired and dozing off throughout the day, sometimes even my eyes get weak and I feel like I fall asleep for like a second. I find it hard to keep my eyes open throughout the day unless I'm being super active. I also have awful memory and comprehension. at work I get information from customers and forget like two seconds later sometimes. I also have depression and anxiety... Idk if it could just be due to my depression, but my biggest issue is my memory. I feel like it's so difficult for me to learn things. I can remember things for a test but it doesn't stick in my brain. 
Are any of you narcoleptic? Could this be symptoms of my depression or could I be narcoleptic which is causing my depression?
