Getting Burned Out!!!

I have been a clinical coordinator over 2 units for over a year now, RN for the past 8. I have worked, Med/Surg, PCU, ICU, ED. This position was to be scheduling for both units, chart reviews, scorecards, PI meetings, training of new associates, and being on-call and fill-in as needed. I have found that just in the past 4 months our turnover rates are going SKY HIGH. I am getting calls during the night for call-offs, going in and working after putting in my time that day already, I am really starting to feel burned out. I am also questioning "Is management really what I want in my nursing career?" My director has a full plate already, dealing with all the administrative parts of her job, like complaints, policies and procedures, staff issues, etc. I am the one that is on-call all of the time, she takes call maybe one weekend a month, but I am every day during the month with the exception of that one weekend. She does help in the units during the day and after I have put in way too many hours in a week, she will step in and do a night shift or two. But I don't know if this working all the time way more than my "exempt" status pays is worth it. I use to enjoy my job, but I have found that I have been contemplating is this really for me???? I still enjoy patient care, however, I feel that I am ready to get out of it. I am looking to possibly going into the Quality aspect of nursing. Any thoughts????
