You

"You" is a drama short film about depression and it's side effect on oneself.
We can see a depressed guy who's stuck on only seeing things one way that he ends up missing any other possible view. His negative thoughts are controlling what he sees and what he hears and changing them from good to bad. He's so sad and depressed that he cannot even realize what's really going on around him.

BUT he started to ask questions about "how to stop convincing himself that everything is hopeless", "how to fill his emptiness" and only then he realized that he was the problem, he was making it worse by giving up. So he started cheering himself up and creating his "Own Universe" a universe in which he starts to be optimistic, to think positively and to see things the way they really are. He then realized that HE can be his Own Healer and save himself from drowning into the void before it's too late.

After all he's been through he became capable of controlling his emotions, his positive thoughts and optimism. He started to see life as it really is full of joy and happiness and even if you're sad or lonely it won't last forever because "After hardship comes ease".
