My guess is that she's mean, negative and snarky because she's very unhappy with herself. Her brain is in such turmoil and she gets to marinate in that all day long. When others invade her space, particularly the ones that she's hurting, she just gets crankier with herself.
Somewhere I read that for as bad as we feel, the WAS feels 3 times as bad.
And while I can be compassionate and a little sympathetic to that, part of me does think, "Good."
