The experienced therapists are right ... it takes about a year to get your footing in the job and to feel confident and competent; a little longer to feel truly proficient. I am an RN (32 years now!) and this is how it was for me right out of school.

College teaches you the basics; the things you need to know to become board certified and get your foot in the door. The nuances of the job are learned after you start working. Until that time, anxiety and uncertainty are par for the course. My first year was filled with worry, anxiety, and uncertainty but gradually I could feel a sinking in of 'knowing' that I was getting better at the job and next thing I knew, I really was an RN ... not just someone with the credentials.

Hang on to every good moment you have at work until you beat in this first year. I am so glad/proud of what I have accomplished and I hope you will be also.
