post-adolescent ennui strikes us all. (sometimes more than once
)
I agree with Lisa: do something. Go volunteer if getting a job is out of the question. Move to another country for a while. Learn something new.
Develop coping mechanisms now, so that when you hit your next bout of ennui you can pick yourself up and dust yourself off and get over it quickly. It's just part of being human. It will pass, but if you can move it along you will have learned something important about being an adult.
