Congratulations, you've re-discovered blogging. ;P

In all seriousness, though, writing does help. The productivity block you're talking about was the reason I started blogging way back in the day. I don't write much personal stuff anymore because I don't need to, and when I do, it's an email to one or two people and that's it. As chrisaycock noted, sometimes all you need to do is observe your thoughts and feelings, and then they get out of your way, leaving you feeling less burdened.
