I understand how you feel. I was "Dear Johned" while in the Service (And in combat at the time). I know you feel llke someone has ripped your guts righ out of you, and left them hanging on a tree. At least that is how I felt then, but I had to stay busy.So beat the drum, sing the blues, Write some new sad blue tunes. Yell at the plastic plants.
Listen to a nice refreashing Polka. Try someting compleatly differant, take a flying lesson.
Time will be the biggest help.
