I definately can relate to the hurt feelings that you experienced during your situation. I am a CNA myself, and it seems like every work day, one out of 11 patients are not happy with something about their care. A couple of times patients or family members wrote a complaint because I wasn't making them comfortable enough, or something along that nature. I remember once I bent over backwards and made a patient my priority, spending extra time comforting her and trying to make things okay. At the end of the day, when I walked out of the room, I heard the patient's husband complaining that I didn't know what I was doing, and that I appeared spaced out! They were not complaining about the MD, the RN or anything else but me and how I did this and that! I started to worry that maybe I would really lose my job and actually broke down into tears. I was so mad at that patient, and could not believe he was actually trying to get me in trouble!
Luckily, I was given some really good advice that has made me into what I am today. What was said is that I care way too much about these people, and I need to start treating health care like it is a business. I had a doctor even tell me, these days it is like how many complaints do I have today instead of compliments. Just do your job, keep up your customer service, set your boundaries, and know at the end of the day you kept your side of the street clean. People will always try and knock you down, (maybe even your boss or co-workers), so never feel guilty for anything you did at work, because you know you got the job done whether or not someone else thought it was good enough. I certainly hope this advice helps you as it did for me.
