Getting Used to a New Trainer and other impossible goals

My trainer quit the gym. Just up and quit with no good reason. I know she has her own life and everything and doesn't exist just to whip my ass into shape, but still. My new trainer is actually the owner of the gym and she is super nice and helpful and there is absolutely nothing wrong with her whatsoever. I think, personality-wise, I might actually like her better. It's just that . . . well . . . you kind of get used to a trainer, you know?
It's a very personal relationship a woman has with her trainer. You tell her things you would never tell anyone else, not even your husband whom you love more than anything. You know, things like your weight. She's seen you sweat and groan through your toughest workouts and she's even measured your thighs, for god's sake! And you actually feel compelled to tell her the truth because you know that her sole job in your life is to make your body better. And that's exactly the way you like it.
Now she's gone and you have to get used to someone new. It's a bit like dating, I suppose, after having been in a long term relationship. I can't imagine anything more horrible. Now all I have to do is manage to carve out a good relationship with my new trainer without growing too attached. I have some serious issues.
My next impossible goal is somewhat more short term, but no less unrealistic. I want to lose 3.5 lbs. by the end of the week. 6 days. Not entirely impossible, but still highly improbable.
You see, I have these jeans . . . and then there's this concert . . . and well, you get the picture. I tried the jeans on yesterday and they actually fit. And fit pretty well, I might add. But I can't get over the fact that I'm hovering at 213.5lbs. and I can't help but feel that the jeans would look even better on me if I was at 210.
I know it's ridiculous, but still. I figure if I bust my hump all week then even if I don't lose the whole 3.5 lbs. I will at least have lost something, and hopefully even have jump started my metabolism so that next week is a little easier on the scales, too.
Call me crazy. Call me a dreamer. Just don't call me for the next 6 days. I will be at the gym.
