Not quite so sure about this nursing career change

My last few night shifts were pretty rough.  I was tired, we were short staffed and I had some patients with high acuity.  Add all of that to the fact that I have been on the floor less than six months, I had seven patients and work with some nurses and auxiliary staff who can be challenging (to say the least) and you have a recipe for a swift exit from this career. 
One morning,  after the midnight shift, I arrived home, showered and plugged in my computer to look for healthcare, IT jobs.  I figure that I can   combine both my careers and escape with more money, a desk (my feet are killing me), more autonomy (I'm so sick of relying on less than helpful people) and less dangers (needle sticks, combative patients, combative family, exposure to communicable diseases).  I filled out a couple of applications in another healthcare system.  There!  I did it.  That was a big step for me as I am the one that stayed on board with EDS until after the shift sank.  I am a loyal employee.  But, for my sanity, I reasoned that I have to change.
Don't get me wrong, there are many positives about nursing.  Money, would be one of them, had I not already earned more doing something else, but the money is decent.  The money is very good when I consider that I am part time.  Where else can I work 24 hours a week and get paid $26.01 base pay per hour?  I earn $28.31 for midnights and $30.31 for weekend midnights.  I still, however, long to earn close to what I was making as a consultant.  Next, I like that once I leave for the day, my work is done.  It was never like that when I was working for HP.  There was always something to do and something to try and figure out.  There were conference calls, meetings and off hour maintenance windows.  The final perk is the patients.  I have met some people that I will never forget.  Many have touched my heart and far outnumber the ones that have gotten under my skin. 
People keep telling me that it isn't nursing that I don't like, but rather where I am working.  I am not sure where I will be led but I am taking some steps and that is a plus for me rather than my usual complain and "stick it out" attitude.  I will just take it day by day and try really hard to like the person that I become when I am around such chaos and negativity.  We shall see.....
