If it isn't something that has afflicted ourselves then maybe it has afflicted people you know. It could also be simultaneous where you have friends who also have some kind of addiction. A place to tell your story about it.
It's important to know that this is way broader than drugs or substance abuse in general. It can also be a habit that one continues to do against one's better judgment. Like choosing to do something seemingly irrelevant while there is something much more important that needs to be worked on like exams. That said, you also have addiction to video games, the internet or even dangerous activities.
As for myself, I've been some kind of addict for just about as long as I can remember. Before I got hooked on the internet, it was video games. There were a lot of things I would brush off so I could play and continue playing. If left without interference, I could play for about 6 hours straight, neglecting my parents, family and even my own physical needs. Fortunately there were plenty of interference. I did do well in school though. In fact, for a long time I had been one of the best students in my classes. If I didn't play, I'd get bored, and I couldn't stand boredom.
Here's where I'd like you to stop and think for a moment. "Boredom". "I'm bored". In the English language, "to bore" is a verb meaning to create a hole in something. When you say "I'm bored", you're also kinda saying that a hole's been created in you. In essence, it is a feeling of emptiness or feeling hollow but most of us don't really recognize it as such, do we?
Continuing. Most of that addiction is the internet nowadays. Whether it's browsing forums, chatting over Skype, looking up articles or anything irrelevant, I've caught myself staying on against my better judgment.
Much about addiction is to hide away or to distract oneself from one's pain or emptiness. Could be one, the other or both. Maybe emptiness itself is painful... Whatever it is I am addicted to, it's hard to stop because that feeling or illusion of fulfillment is only temporary and wears off rather quickly...
So what's your story?
