Futureless

After some long, somewhat revealing conversations I had last night with some friends, I'm just lost and sad.
I don't know what to do anymore with my life. Or how to act. All I know is the things I've always secretly hoped for will never come true.
I had a moment like this a few years ago with another friend. One morning I woke up and just knew that I couldn't keep loving her. And so I stopped.
This revelation isn't quite like that one. This one leaves me lost, not liberated. I've been living a shell of a life all based on the foolish hope that she'd develop some desire for me as well.
Now I don't know what to do. I'm at a point in my life where I'm supposed to be deciding what I do for the rest of it, and I'm realizing all of my choices until now have been wrong.
And it scares me. Because now I don't know if the right choice is to enjoy my life or go the path that puts me in a job that I can make a career out of but I have no real want to do. I know the choice others would want me to take is the one that is safe. But in the end will taking the route to the job that I hate or dread for the rest of my life be just another decision I regret?
