Welcome to DC! I know nothing about working in a kitchen but I've worked some other high stress, make it or not jobs and it's all pretty much the same. You throw everything you have into it and try to keep positive while secretly agonizing that you're not keeping up or holding your own or you're going to end up as "the useless one". Then one day you realize you're just doing your job, you're keeping up, people like you and you're not fretting about it anymore. And you think to yourself, huh, when did that happen? That's been my experience at least and the experience of a lot of other people I've talked to. Just keep at, keep the positive attitude and you'll get there. :)
Just because something has a duck bill doesn't mean it's a platypus. It might just be a duck.
