Sleepless, hopeless

   I fear somethings wrong with me. Tonight I got almost 9 hours of sleep. I'm still tired. I have lecture in one hour, and I'm honestly considering staying home to sleep instead of going, that's how tired I am. It's been like this for weeks, so it's nothing new either. I'm just in a constant state of "I need sleep". I'm really starting to worry about my physical health, because sleeping this much and still being tired isn't normal for me. I usually get 5-6 hours of sleep, and I'm perfectly fine. I honestly don't have side effects from "sleeping to little", but now I can't seem to get enough sleep.
   I'm considering checking in with a medical professional, just in case. I don't want my sleepyness to interfere with the upcoming tests, and I really need all the energy I can get to be able to focus on my studies. People might say the university years are the most fun in your life, but I honestly feel like the university is also one of the most stressful and timeconsuming things I have ever experienced. It's still perfectly do-able, but I suspect it won't be if I stay this tired.
   Unless my constant sleepyness reclines during the weekend, I think I'm going to call a doctor, because this is ridiculous, I'm not getting anything done because all I really want to do is sleep. I constantly tell myself "I'll have a nap, and do it later". All that really happens is, I have a nap, and I accomplish nothing but get more sleep.
   What do you do to stay alert/focused? All tips are greatly appreciated!
Sleepy hugs from my apartment!
