Crying feels so liberating?

I've recently gone through some "bad days" and just when it seems like it cant get worse, it always does. I couldn't help myself today when I got home from work. I just bawled my eyes out, and crying felt so liberating in a way. I still feel the pain but crying helps ease it in some way. Any experiences? What do you do when you're at a really tough time in your life and nothing is going right.
