Oh yeah. My rule of thumb is that the first couple of months in a new job can feel miserable just as you describe above. Don't worry about it, you'll get through it and suddenly you'll find yourself being productive and happier.

I've been working for decades in multiple jobs, and it's always the same. Sure as you progress you know more, but you also lift your personal standards as well to compensate.

Stick to it and you'll get there!
