Hormones? Or actually sad?

Sometimes I have a hard time figuring out if my ugly crying is hormone related or actually something to address in my life?

It happens rarely. But when I break down....I break down. In a very loud ugly cry for a few minutes. And then I feel drained. I'm about a week away from my period so I don't know if I should express my feelings or just chalk it up to hormones.

Does this happen to anyone else?
