I am in nursing school
, and I, too, have my serious doubts about the career. I understand the feeling of being trapped in nursing, it's very hard to cope with!
Fortunately, although I am unsure of nursing, I have met some great role models in the past year who have shown just how wide the range of nursing really is. If you are able to go back to school, try taking part-time (or full-time, if you can manage) classes to get an advanced degree like Clinical Nurse Specialist or Practicioner.
My mom is an Oncologist CNS and has a cubicle office job from 9-5 and has absolutely LOVED working there for the past 20 years. She works for a Physician Referral Service at a top-ranked hospital, and provides tons of patient education and care management over the phone, e-mail and fax. She gets all the satisfaction of making a direct, positive impact on patient's lives, and interacts with patients and other health professionals from 9-5 just from her desk. I give her a lot of crap about it, I say she's more of a secretary than a nurse, but hey--she gets to use her degree, loves her job, and has no direct patient contact! She doesn't even work in a hospital!
I know that's just one example, but maybe it's something you can enjoy! I have to admit, there really is a great deal of options with a nursing degree. Not all hope is lost!
