What if the air we breathe is really a drug that makes us see a dazed version of the world but when people take real "drugs" and trip they see the real world and that's why they're illegal?
What is "real" is relative. Because nearly everyone sees things to be one way, those who don't see it that way are living in a world that is "fake" to everyone else. Therefore, there is no "what if" to it. What is real to one person is not the same as what is real to another. What we call "reality" is simply the illusion of the majority.

Are you dying? Do you have food? Do you have friends who care about you? Do you have a bunch of chronic health conditions? Did you wake up today to freedom or bondage? Do you have things in your life that make you more comfortable? A place to live? Clothes? Heck, you even have luxuries like internet!
You have thousands of things to be grateful for, and yet you say there is nothing good in your life.
THAT is why you are sad, and that is why things don't seem to get better. When you ignore the good things, no amount of improvement will help how you feel.
you're right...being negative doesn't help..thanks
