Is it so wrong to get so bored with your life that you just want to fucking run into traffic?

Maybe it is.

Is it my fault that my life isn't exciting?

Probably. I'd rather not see it that way though.

But as long as I am surrounded by predictable people, generic gatherings and nothing remotely stimulating, I will imagine flinging myself into an oncoming 18 wheeler.

I'm not suicidal.
I'm just bored.
