Well, for heaven's sake, what a jacka$$. This is when the old line about "I may be heavy, but I lose weight. You're ugly (clearly inside AND out) and that's a shame" would be great to use, but you're probably too kind for that.
You know what, you are already an amazing person. You decided to take control over something and you seem to be doing it at a very healthy manner; you know you need support right now and you have the courage to ask. You made yourself vulnerable in a place that you knew was safe. I say, ROCK ON and good for you. Whoever she is, she's stuck there. Too bad for her.
