I'm hesitant to even say this because I know that there are people who read this that suffer from it but depression scares the hell out of me. Feeling like there is absolutely no light whatsoever at the end of the tunnel is something that I can only imagine because I am completely unfamiliar with it. I am an inherently cheerful person, more so than a lot of people, I can't understand the idea of being so sad that you have no hope of being happier other than your rational knowledge that this is not going to last forever.
Mutated vegetable also kinda scare me... But not as much.
