Did I choose the wrong profession? Horrible Anxiety

Anxiety to that level does not sound like it is caused by the job, more that you have anxiety as a medical issue that is being triggered by the job. I am willing to bet if you were an underwater basket weaver these panic attacks would still be there.

My first recommendation is that you see a professional about it, start with your gynecologist since your pregnancy could be playing a role.

My second recommendation is to stop, think, and breathe. The fact that you reflect upon your mistakes makes me believe that you will be a fantastic nurse. The nurse that thinks they can do no wrong and does not reflect upon their mistakes is dangerous. Every Time you make a mistake, every time you feel foolish, every time you express professional self-doubt document it. Write down the issue, asses the issue, develop an action plan, implement that plan, and then evaluate the outcome.

Mistakes happen, what you do about them is the important thing.

Are you sleeping well? I have found that when I worked nights I couldn't sleep at all during the day and it made me feel terrible. I had difficulty thinking straight and handling any kind of extra stress or pressure was just too much. However, if I had enough sleep everything was fine. I know for me, I simply cannot work night shift for a prolonged amount of time. I agree with Asystole, that feeling concerned is definitely a good sign, and is totally appropriate. You have lives literally in your hands, and so much to learn, so of course that's going to make anybody nervous. Continue looking for a new position and/or a new specialty that may be a better fit for you.

I actually sleep pretty well. I bought black out curtains and it basically keeps me asleep all day. I think a lot of it has to do with missing out on things throughout the day. And I rarely see my husband. I've had anxiety all my life so it's nothing new to deal with. It's just the intensity before work has gotten out of hand. I miss working for my old boss at a job that wasn't healthcare related. I felt like I made a difference where I was. I feel like just another abled body at this job. Maybe it's my environment and shift. Idk but it's interfering with my everyday life. And I know it's affecting my husband.
