You posted this a while ago. Have things improved for you?

I started a new job 6 weeks ago (almost), doing the same type of work I've done for years (worked at the same place 23 years before). I'm having trouble not making stupid mistakes...I'm nervous, but I should know better. Beginning to think I'm too old and never should have made a change.

I'm feeling horrible...dumb, incompetent and everything else.
