The Cry Marathon

I woke up that morning and began to cry and cry and cry and cry and cry. I stayed in my home the entire day because I couldn't stop crying no how, no way. I guess everyone cry's occasionally, but all day, all night continually? I guess I stopped crying when I fell asleep, but I think I kept crying even in my dreams, and the oddest thing about all of this for sure is that I have absolutely no idea what I was crying for. I think that this possibly may be a symptom for what doctors would diagnose as clinical depression.
