HI Moonglow, I recently went through the end of my first poly relationship, I was completely crushed and am still not able to focus at work (as evidence my the fact that I'm reading this message board during business hours, lol).
I went to see a psychologist and am so glad that I did. It was so cathartic to talk out all the stuff going around in my head, to someone who guaranteed confidentiality, and who doesn't know anyone involved anyway.
I know that it's a really personal decision but if you can afford it (or find a sliding-scale community center) it's worth a try. If you didn't like the attitude or the prices of the first counselor you called, then call another one. Don't give up!
