Bored with everything?

Have you ever gotten to the place where you are bored with everything and everyone? I really feel like I have. Nothing is exciting, interesting, or worthwhile anymore. I feel like everything is pointless. I feel like I am constantly bored, and everything that I do bores me, but I don't know what better to do. Does anyone else feel like this? Is this normal? How did you find something that interested you again?
