What's the difference between Absurdism, Existentialism and Nihilism?

Who are some actual Nihilistic Philosophers/Authors? Do they even exist? If not, who are the closest to it?

Be honest with me Mr. Gardener, I know you're here, do you make enough money to survive by selling your books? I'd like to write a book too, I don't care if they don't sell, I want atleast one person to read my thoughts. But a man's got to eat, so can you make enough money to survive by writing?

I'm talking about genuine ones, not /x/fags. These days, I find myself completely lost due to excess information and my inability to differentiate truth from lies. I lack the basics. So I was thinking, surely our wise ancestors dealt with something similar, and they must written about it. What are some philosophical books on it?
