I write facebook notes, and before that bebo notes.. A bit like blogging really.. Its all cryptic, so no one really knows who or what its about, but its all from the heart and it gets it all out!! Its worth a try, I always feel so much better afterwards.. If you don't feel comfortable doing it publicly, just write it down in a diary or something.. Once you get into the swing of it, you write without really thinking and a lot of the time I'm shocked by my own feelings!!
Hope you find a way soon.. PM me if your ever feeling too down, I love to help people
