Hey flutterby, sorry to hear you're feeling bad. I felt like that yesterday and had a lot of anxiety at work and was constantly almost breaking into tears.

When I got home I just started crying and went on for half an hour and it worked wonders. Sometimes it is necessary to let all the pain out. Another thing I do when I am depressed is watch movies that distract me from my dark feelings and I listen a lot to audio books. When the pain is to big it helps to escape to invented worlds, even though obviously at some point you gotta go back to reality.
