Oh God!
girl, don't take it to heart. Anonymous dickwads are naught but spineless cowards with nothing better to do than to try and hurt people from afar. If they had any real balls, they'd step up and say what they have to say instead of hiding behind an anonymous email.
I know it's hard, but let it go. Forward the email to Lens and see if he'll help you. Best to you and that precious baby!!
