OK, here it is. Even if you love so many aspects of nursing--even if you you have found your niche--even if you really strive to have a great attitude--um, a person can become miserable in the role for a good many reasons. So, if you aren't into it, please consider not doing it.
IMHO, there are already too many disgruntled, burned out, miserable, and just unhappy nurses in the field. Some of that came for them over time, and for some folks, well, they thought it was going to be something other than it is.
On top of that (and I truly expect to get slammed for saying this), there are too many insecure people in the field. No, not all.
Many people just aren't in touch with their lack of ability to work together, be flexible and supportive of each others--regardless of clique or faction formations--that is, they don't get the concept of forming coalitions with other nurses for the ultimate good of nursing. So, they can't find common ground toward that aim and choose to work together without infighting. There are some that just strive to be on top of their game, but can't do so without trying to intimidate, manipulate, or out-do others.
And then there are the poor folks that just want to do their best, but are wrongly viewed as being competitive and vicious ladder-climbers, when indeed that may totally not be the case. I'm always amazed at how much jealousy there can be in nursing. I scratch my head, and I really don't get it. There are a lot of nurses that don't get the whole "You're OK, I'm OK" thing.
So, there's this gross lack of security, objectivity, balance, and fairness in the field; that is, IMHO--and I think after 20 years of hard work and striving to do right, I am entitled to my opinion.
Unless something has really changed within you or you just think you didn't give it a fair enough shot early on--OR if you think you were more on the young and immature side--don't go back into the field.
It's not worth it to make maybe $20 extra per hour. $15/hr(40 hours) is about $30,000. $30/hr is about $60,000. That may seem like a lot to some folks, but it's not really--especially if you are miserable doing something, are working off-shift & holidays & weekends, are dealing with all kinds of stress and getting your hands dirty. You have to be OK with all that, plus the sad disunity that may accompany the team or group with whom you may end up working.
Get something for now that will help pay the bills and go back to school for something your really like--and hopefully is more marketable.
Education can be a political pain in the butt, but if you like it, and are good at it, there can be many more benefits to it than working in nursing.
Or, perhaps if you go back to nursing school, and then you could also work on getting a school nurse certificate--or try occupational health. You really have to do your research and take some time to think about it--after doing your homework (research) that is.
Good luck to you!
