I have depression, so yeah, I do cry a lot - more frequent lately as I have been feeling down 
Flat effect for me has no range of emotions. I don’t even cry when it’s appropriate to do so.
I don’t cry as much as I used to, because I feal deadness in emotions, but if the voices are plaguing me or I have a bad argument with my husband I may shed a few tears. Or maybe reading a heartwarming book or watching something touching on TV may get a few tears. I rarely sob, it has to be cataclysmic for me to sob, but when I do I can really let go and wail my heart out.
