Will it be ridiculous if I ask my doctor for a sleep study?

My tiredness is getting worse.
I'm scared to ask my doctor or tell my doctor about the tiredness because I'm scared he will think it's silly. Also, everyone gets tired? But do people get overwhelmingly tired? Falling asleep driving and stuff.

I looked into narcolepsy. I do seem to have symptoms, but I've seen a documentary before where they fall asleep during work and stuff. I don't seem bad?

I haven't been at work or school in awhile.
Although when I did. Going to school I would fall asleep driving or fall asleep in class. But I thought that was normal?

If you ask me how I feel any day, most likely I will say tired.
I need naps everyday. I can sleep 20+ hours. Still be tired.

I got my blood checked before for a basic exam starting Medicare. Nothing abnormal besides cholesterol a little high.

The past couple weeks have been bad. It's extremely hard to stay awake during the day.

I would think it was medication side effects but I think it's something more. With or without medication this happens.

I just feel ridiculous asking the doctor about it.
Because when I think of narcolepsy I think of someone falling asleep anywhere anytime.

But the sleepiness is getting out of hand and I get made fun of how much I sleep.

I'm 21 by the way.
