The Strangest Friend

Does it make sense to desire wanting something you know is bad for you? Even with the countless warnings and studies and books and blah blah blah... When it's the only thing that makes you feel complete... When it's the only thing that makes you feel in control... The only thing that makes you feel... But it's hard to even want it. It's hard to commit. But you know, if you try, it'll stick. And for a couple weeks (at best) you will stop feeling so lonely. I'm not sure if the word, "addiction" fits. I guess you can be addicted to anything. Even sickness.
