Please continue with your plan. You don't say what motivated you to become a nurse, but someone who is feeling downheartened at the prospect of NOT becoming a nurse must have what it takes to be a good one.
Perserverance, above all, is probably the single most important thing about being a nurse. Of course a good attitude helps, but one who perserveres can ferret out information, keep difficult situations from becoming impossible, and see the silver lining in a gray day.
Right now, Nursing is in a "gray" period. There is nothing like a nurse-not a patient care tech, not a computer, not a robot, and certainly not a doctor. Nurses use all of their senses, all of their education, and all of their intuition, every day. It is all so integrated that nursing becomes a way of life, not just a profession. If you have an affinity for helping people, you like a constant challenge, and are not easily intimidated, nursing is for you. A lot of it can be dull, and routine. You are rarely, if ever, appreciated by your employer. But-if you can start an IV on a neonate when nobody else can, or ease the fright and pain of an evolving MI, or provide some measure of comfort to a husband and wife who are experiencing a miscarriage, or offer a hand of comfort or relief in untold other ways, and derive satisfaction from being able to do these things, you are cut out to be a nurse. If you are looking at going into Nursing to make lots of money, work in glamorous surroundings with sexy Drs., and zoom quickly to the top of the profession, start looking now for an alternative.
