So I'm a trooper, then... No, I don't deserve a title like that, since it wasn't a chore at all, really Julia - give yourself some credit.
Well, what little I can say is - I know how you feel. I'm sure basically everyone does, in some respect. Going through times when you're not all there, and life feels like a level plane with no significant valleys or hills, just trudging along... hehe, not to sound like Marvin or anything...
I guess about the only advice I can give you is what you already thought; to do something out of the ordinary. It could be something like taking a hike in the mountains, going on a little trip like you said, maybe stick up a convenience store with a bag of snakes, eat shrooms and do a big oil-painting... the possibilities are endless!
These are just idle, please-do-not-try-this-at-home suggestions, but yeah... I suck at giving advice, did you know? Good luck with your life anyway, I'm sure a smart girl like you will find a way to resolve the situation, or lack thereof.
