Acting on the assumption that what you're saying is true, I'll tell you a story:
When I was around 17, I was homeless in my own hometown, with nowhere to go, nobody to see and nothing to do. I remember standing on a corner one time with literally no reason whatsoever to go in one direction or another. It just didn't matter. I couldn't go any lower, I couldn't have any less reason to live, nothing I did had a point or a purpose.
Things get better, you just have to suck it up and keep marching on, trusting that one of these days something good will happen and you'll see a great flaming arrow telling you which way to go. In my case it was the National Guard, then college, then meaningless job after meaningless job until I found porn. Now I'm still depressed, but I'm rich and I have lots of friends
If you or anyone else is truly feeling down and out during the xmas season or any other time, my icq is in my sig and I'm easy to reach. In the end, all we really have is each other, the rest is just window dressing.
