Confidence Crisis

I am thinking about setting up some kind of interpreting practice group - practice sounds weird in this context, but I don't know what else to call it.

Since I don't interpret all day every day, I feel like I'm in a vacuum and I want to interpret some stuff with other people around to give me information/feedback/support.  At the same time, it is terrifying to think of it. I've been an interpreter for a long time but being out of the loop there is always this little, niggling voice saying that I don't have it anymore.  I want to shut that voice up.
