I agree with your nursing instructors in that you need to get your anxiety under control. I too have had difficulty with anxiety and I've been a nurse for 28 years. I started back to nursing three short years ago after staying home for 18 years to raise my five children. There was a lot of concern on my part about what I would be able to do. I must say though, it wasn't as bad as I thought it would be. I don't like acute care/hospitals though or maybe I didn't like the facility in which I was working. I'm currently looking for a position as a wound nurse in Long term care, because I love old people and I love wound care or a Private duty/home health nurse in Pediatrics. I have also taught nursing students at the LPN level. You have many life skills that you can draw from as an more mature person in making decisions etc. This makes you an excellent candidate for being a nurse. Lacking confidence is only gained by doing what your afraid of. Unfortunately, we have, at our age, a lot of fears in our memory banks that come out to haunt us. If you really want it, go for it. There are nursing jobs out there that you would be good at. Confidence comes from doing. Read Wayne Dwyers book Erroneous Zones or John C. Maxwells book Failing forward.
