I recently started a new job in a different field. I thought for a very long time before accepting the position and based on the training program and reviews from employees I accepted. Now I'm through the training and doing it for real and my anxiety is out of control. I'm so afraid of making mistakes, looking a fool or incompetent, or just disappointing everyone. Where do I find confidence? Why can't I accept that a new job is a learning experience and a good thing? I'm tired of the fear. It's always there, now it is just more overwhelming because of the new job.
