I used to listen to my old angry punk records, or a song or two by Bauhaus.. then am showing my age.
The other thing I do, is allow myself just one really really miserable night, thinking about them. Then get a bottle of champagne, drink it all myself, and burn photo's! Not as drastic the last bit as may seem, coz I always had the negs, lol.

I hope you feel better soon - and be kind to you. Its always hard.

ps - I like the present shooting!
