Right so I’m one of those people who never classed themselves as an early morning person, but for school, I’ve been sleeping at 8 and waking up at 3, which is actually decent. 
But for some reason, I’m always tired. I want naps, and when I take naps I’m constantly tired after - I’m certain I wake up during light sleep in my cycle, so I’m unsure why I’m always tired. 
I’m on fluoxetine and have noticed that ever since, I’ve been tired. This is when I decided to wake up at 3am for school to study prior. Last night, I just wanted a nap from 5pm and woke up at 11am today. 
How- why is this happening? 
When I tell my GP, it’s like they don’t take it seriously but I’m honestly scared I’m going to fail my exams because Of this constant fatigue.
