I have been on a crusade to cry latelly.
I've been reading the crap out of this site and others like it, watching sad and nostalgic movies, listening to emotional music, walking to places with outrageously beautiful vistas, thinking about lost loves and memories... All in an attempt to cry.
I don't know why, but I really feel like I need to cry. it's been a long time, nothing really bad is or has happened recently. I don't know why I just really feel like I need a good cry. The best I can do is tear up. Then I try to concentrate on what it is that's making me tear up, and then it passes.
