Without going into the detail that linkan has, I too, am far to busy to be bored.
Lowwow, you managed to spend enough time on your computer to find this site, there are many many other sites that can cater to even the mildest of interests for you.
If television is an important part of your life, why not find a site that discusses your favourite shows, or shows that you used to like but aren't screened anymore. You may be able to offer some information that other people don't know about. The same with any sports that you are interested in or watch on TV.
The Internet is a wonderful place, not just for chatting, but to learn about things, maybe even help you with your homework.
Believe it or not there are even sites that you can visit just on 'boredom' itself.
You might be a bit depressed, but by doing something for someone else, you are doing something for yourself.
Good luck!
