Good golly. It's like "Who shot J.R.?" (circa 1980) all over again.
If I was in your shoes, Stephanie, feeling they way you are, I would sit down, write a list of 5 things I love about myself (so that I'm feeling a teeny bit more secure), and then I'd open the email, and no matter what it says, I'd make a list of 5 more things I love about myself (for the reassurance value).
But that's just me.
You go girl!
