Hey, I am sort of in the same boat. For me, it is a lot of anxiety over whether they really understood what my skill set is. As time goes by, it's getting better. I understand that my anxiety/paranoia is really just something *I'm* thinking about. It's getting easier to tune out now that I've been there a couple of months.

Someone in another thread suggested that I remind myself of the value I bring rather than focusing on the stuff that seems overwhelming. That has helped.
