Depression is what I feel when the attitude you approached grade school doesn't work in and high school. And your labeled as a "spazzy freak". And not even the losers of the school would talk to you as an equal.
That feeling of going home everyday to be reminded that you have to go back to a place that only makes you feel like a piece of shit.
That feeling when the unhealthy habits you take up to turn you mind off from the pain only makes it worse.
That feeling that no one will accept you for being an atheist, with teachers telling me that I'm going to hell for my beliefs.
That feeling when you parents think that the devil is controlling you, and are finding ridiculous ways to help.
Depressions is when the projects you take up to keep your mind off the assholes, are destroyed in front of you by them, and having those asshole laugh at you for "crying over spilled milk".
Four years of my live were spend like this until I decided not to take anyone shit anymore and stand up for myself. Depression is something that has shaped me into a better person, I think I understand it.
