SleepingBeauty

I'm not sure if these things have anything to do with each other but the fact that they're occurring all at the same time is too much of a coincidence. I am nineteen and have NO possibility of being pregnant. My period is very inconsistent since I started when I was twelve. I've gone to doctors and had tests. I've vomited before because the pain has been so intense. As I've gotten older the pain has lessened but it remains irregular. I am quite late now but I've noticed other things that are not normal for me. I have a tendency to like to sleep. However, for the past two weeks I've been sleeping CONSTANTLY. Last night I slept for fifteen hours alone. EVERY night I get sleep paralysis and I'm terrified to go to bed for fear that I won't be able to wake up. I am also eating CONSTANTLY. No matter what I eat or how much it seems I have to just keep on eating. I don't know what to do. Someone please help me in the right direction for steps to take.
