I got to be very tearful all the time, embarrassingly so. I would be crying uncontrollably several times a day - and it would take little or nothing to set me off. In my case it was part of the depression, and I found that going on an antidepressant helped me to function better and to keep my tears under control -- now I only cry when I'm really, really upset. And sometimes, even if I feel tears coming on, I can stop them -- that was impossible before, it was like opening a flood gate.

I've also found hypnosis/relaxation techniques to be very helpful in calming me down, and I've found since that I can be more analytical about things than I used to be, instead of having an emotional reaction... at least on a good day
