I am very glad I was able to help put your mind at ease. This field isn't always easy, patients (and families!) will sometimes say mean things, sometimes there is chaos, and occasionally threat of physical violence (though in my experience it more often stays at level of verbal threat - but in my world we take even verbal threats very seriously), and exposure to some absolutely heart-breaking stories and past trauma. I agree with Here.I.Stand -- assault is assault - workplace violence or not, and my workplace can and does report assaults - be they against other patients or against staff - to the police. Even when a reported assault was unwitnessed by staff (and potentially questionable to have occurred due to unreliability of patient) we will start an investigation because our patients deserve this, and our staff deserve this.
I do think that online forums can skew towards the negative (including this one) because people are more often going to "vent" online than to post their major successes online. Perhaps because of the anonymity (real or perceived) online forums offer. There are also a number of RNs, who, for whatever reason, have become extremely unhappy with this field and who will actively try to discourage new RNs from joining.
Nursing is not a perfect job or a perfect field. There ARE negatives involved with this career path, but I would argue that is the case for ANY career path or job. It's about finding the pros/cons that you personally can live with - and with in nursing there is still room to move around - different specialties and different facilities have their own pros/cons as well.
I see you are considering counseling for anxiety in another post - I do recommend this not only for you but for anyone considering a major life change (of which starting a new career is one!). I personally struggled with severe anxiety in my past and have intermittently seen a counselor (and been on medication) -- it was a big help both prior to nursing school, and during nursing school, to have some one to process the experience with and to work on my own self-knowledge and self-growth. I will also say that nursing school seems to be a HIGHLY anxiety provoking time for many, and several of my peers who did not have anxiety issues before nursing school developed severe anxiety while in nursing school. Ultimately I am far less anxious now (working in a setting that many people seem terrified of) than I have been at any point earlier on in my life.
