I hope I just finished going through something similar....

I was dealing with serious harassment from my boss -- he lied to people to get them to see things his way, he didn't care that he made me (and anyone in the room with the two of us) uncomfortable, and he did his best to isolate me by lying and saying people were afraid of me. (Just to note: I kindly checked in with the one person I figured out he was talking about and asked if they were scared of me because I didn't want that to be the case. No surprise, my boss lied.)

ANYWAY, I was super crazy immensely stressed out for months, even to the point of needing 1 FMLA leave and contemplating a 2nd. I went from never crying to crying over the slightest thing. I begged my psychologist to help make it all stop but she suggested it was a good thing, even as I sat there crying and with indignation argued/logic-ed with her that crying served no purpose.

End of the story: As I was driving away from work for the very last time, I cried my eyes out for the entire 45 minute drive home. I hated each and every second of it. That being said, it's been 4.5 days and I haven't cried since. Either that's a new record -- and I didn't cry over things that would have made me cry about a week ago -- or maybe it's over? I still don't understand the connection of stress/emotion release via crying but it does seem to be connected.
