If you enjoy helping people, enjoy a challenge, and want a change, then nursing could be for you. I've nursed for 15 years, with a two-year break due to ill--health. I can't say I have loved every minute, but I am a better person for the experiences I've had. I love being a part of sombody's recovery. I love making someone feel more comfortable physically. I love being able to make somebody laugh in the middle of their pain and fear. I love connecting with people when they are vulnerable, and being able to lift their spirits, speak a truth to them, or pray with them. If I go home and know that one person is better off for my being at work, that's a good day. I love being able to advocate for somebody and get them the pain relief or treatment they need. As the saying goes, with knowledge comes responsibility. I have knowledge and experience, and will use this to help my patients who may not understand what is happening, or be frightened to ask their doctor the hard questions.
The difficult side of nursing is inevitably linked to the good side. If you want to spend time with somebody, you usually have to do it after your shift, because you are flat-out too busy to do anything more than the basics. I hate running into a patient's room, and the first words out of my mouth are: "I'm sorry, but..." this could be "...but my other patient just came back from surgery", or "....I couldn't get your medications to you sooner because Mrs Smith needed the toilet", or any one of a million other reasons that delay me. I hate the pressured feeling that comes so often when you just HAVE to be in three places at once, and you then make the decision which of your patients gets attentio first. I hate the feeling that comes when I realise I haven't given my best, and a patient has been in pain or afraid.
Pay is good, yes, but not fantastic. (At least in Australia.) I get good wages, but not in relation to my knowledge, and experience. I have 15 years experience, an under-graduate diploma, a post-graduate degree, and a post-graduate certificate, all in nursing. The decisions I make while working can have an immediate effect on a person's life, not to mention their family's. A labourer gets the same rate of pay per hour as I do. No, he doesn't get shift penalties or weekend loading, but then he does get the choice of spending this time with his family.
Shift work is a necessary part of nursing, at least for the first years when you get experience in a hospital. Yes, shift-work is difficult, and plays havoc with your personal and family-life. But then you do get the odd day off in the middle of the week to go shopping.
If you are prepared to dedicate several years of your life to study, education and a total life-change, then nursing is immensely rewarding.
Best of luck with your decision.
