*hugs* Maddy, if it helps...I've been working at my job for three years and I still make mistakes. It doesn't mean you're dumb by any means, because I know you're a very smart, sensible and intelligent person. It'll just take a bit of getting used to--and like you said recently, you're probably PMTing, so I wouldn't worry TOO hard on it.

I usually find that a good bitching about work helps you feel better, especially if you can find some fault in the customer or your co-workers and blame it on them. Between having a moral dilema and feeling absolutely shitty about yourself, I'd go with the moral dilema. That way you feel confused, rather than depressed.

I really hope your job picks up. I'm here if you need me. =|
