Sometimes... and this is just what I believe, understand, sometimes, all you can do is start over. Pick something new, and do it, discover it, go to it.
And you just... do it. It's hard, and it is scary, and it is sometimes more frightening than what you face, but... sometimes it leads to better days.
But, whatever you choose to do, there is no reason for you to be alone to do it. Do you have friends to talk to?
