Jealousy overcomes me, and I'm  embarrassed and ashamed of it.  How do you handle jealousy?  What tricks/tips do you have? 
I was pregnant within a few weeks of my good friend and coworker, who is now rocking a cute bump.  I lost my baby.  It's so difficult for me, especially now that everyone is making such a fuss over her.  She tries to offer words of support, but they always seem to leave me more angry & frustrated.  I've started avoiding her (and everyone else, really - I've become a bit of a recluse) and it makes me so sad.  I'm happy for her, but I'm also grieving over my losses.
