I began journalling online because my friends invited me to. I continued journalling online because of the strange relationships you can have. What I mean is that you can say everything you feel in a completely cryptic way online, and no one cares. You have people around you who care enough to read what you write and comment in a helpful manner, but they will probably never know you. I have been doing it recently less for the writing, more for the strange "I will never know you, but I will spend all week commenting in your journal because I care about you, unknown internet stranger" relationships. If I want to get things out, I usually write or draw things. I think I know what you mean with the writing you did. About spending so long wanting something, then before you really realise that it's slipping away, it's gone. It bites.
