First: Hugs and Feel Better and don't stress too much!

Second: Whether or not you were having a bad day, you were completely justified in what you said yesterday. A person's looks have absolutely nothing to do with their talent or their crazy or anything else, and it's harmful to rip on someone's looks just because you don't like them. It's also petty, stupid, and weakens any other argument you may have.

You're dealing with all this way better than I would be able to. You're doing great.
