I Love Nursing.
Does it Suck at Times? Yes. But then again, doesnt every other job?
Remember, a lot of us come on here to vent about a bad day, bad manager, bad situation, etc. I think (I hope) you would find that most nurses arent in it for the great hours, or the great money - we're in it b/c we love what we do and helping others.
Sure, the politics of it sucks, you may get a bad assignment, have a family member whom you swear is the spawn of satan, or any other bad combination of things that can cause the shift to be horrible. But in the end, it all boils down to helping someone overcome an illness.
Am I stressed at work? You betcha! However, nursing school has prepared me for checking med dosages(and many others things), and also realizing that someone else is always there to help me, even if it takes a few minutes and it means an antibiotic is hung late. Its not the end of the world. There are drug guides and references everywhere. I have to look up half of the drugs that I give.
I think that until you find your niche in nursing, you wont be truely happy. I think that after 2 years, I've found it. I've gone to a pedi step down unit, and am on week 4 of orientation. (its inbetween PICU and floor nursing). I love learning, and there is so much here for me to learn and do.
When I first graduated, I had no clue how to do things. It all comes in due time. You dont come out of nursing school knowing everything, and contrary to popular belief, you dont come out not knowing anything. You do know things, and it will take a while for that confidence to show.
You've already put 3 years into it, why quit now? If your anxiety is really bad, I suggest a visit to your doctor to discuss your options.
I think that I slightly rambled in this post, but I hope you found some part of it helpful..
