Tears won't flow.

I have been watching numerous sad movies, series, whatever I can find. I have been listening to so many sad musics. I have watched the saddest episode for Doctor Who. I still can't seem to get these heavy tears of anguish, pain and sadness flow. Everything is balled up into one huge dark ball, ready to be released. But why wouldn't it release or go away when I want it to be. It is so heavy, keeping it to myself like this. The feeling inside is so painful I really hope i just ask it to go away. Please just go away.
