I am so sorry that you have to go through this. The sad part is no matter what you do, it will still hurt. When I start to wallow these days, I have to get up and do something. I repot plants, rake leaves, try something crafty. Lately the best thing I have done is volunteer to coach soccer. It gives me such a warm, happy feeling. Just do anything to give yourself a feeling of accomplishment.
I alos think that when things get really bad, Ben and Jerry are still friends of mine, I just don't eat the entire carton(s) anymore. Half will usually suffice.
I hope your heartache ends soon. Remember that when things go wrong it often precludes something much better. There is a better man out there he just hasn't been lucky enough to meet you yet.
