Does the anxiety ever get better??

I have been a nurse for 14 months now. I worked at one facility for about 5 months, 2 of which I was not licensed. To make a really loooong story short, it was a horrible experience and I ended up quitting. After I was told "you ask too many question", and " You will sign off on the narcs for the unlicensed nurses". I felt very defeated, and wasnt sure what happened as far as me asking too many question, I mean I was a BRAND new nurse. At the end of me working there I was so anxious, so worried about doing everything the right way and such. I finally quit.

Anyhow, I applied to some places and got a job the next week. I have been there going on a year. It is by far a way better environment, lots of help when needed. However, I am still anxious. After I have not been there a couple days I get all worked up when the phone rings, I am worried I screwed something up and they are waiting to bombard me with it. I am always worried I am going to miss something. I am a people pleaser and find myself taking blame for things I didnt do just to avoid conflict.

Does the anxiety ever get any better? Is it a matter of feeling confident or does nursing just do this?
