So I need some advice. I started a new job recently. I was new to working 12 hour shifts and it was only my second time with 3 days in a row. I am definitely not making excuses for myself at all, but I fell asleep twice that day. Once during a meeting in front of every charge nurse in the hospital and the Nursing supervisor and another during a patient group while shadowing the social worker running it. The strange thing is in neither situation did I know I even did it. The social worker confronted me when I proceeded to tell her I loved how she ran group (like I said honestly thought I was with it) and she told me I was asleep. I visibly almost began crying and stated I felt unprofessional, disrespectful, and I didn't feel sorry even began to cover it. Then I proceeded to tell her I was getting a heart monitor the next week as well as a sleep study soon because I hadn't felt right lately and had been sleeping profusely on days off. I then was off for a seven day stretch to come back to my boss wanting to speak to me. I hadn't had a chance to seek her out first as she had been busy the day it happened and the seven days left plenty of time for it to get to her by my coworkers. Come to find out, one of the charge nurses who didn't even know my name also called my boss to report me. She never addressed me personally or anything. I explained to my boss what I explained to the social worker. Not giving excuses just the facts of the situation. I guess I was really hurt and felt unsupported that I was reported by one who didn't even talk to me about it herself to at least see if there was some explanation and by another who didn't tell me she was reporting it and I also did explain myself the best I could. I got a disciplinary warning in my file that sounded pretty awful, but my boss was genuinely supportive. I guess I am just seeking advice on where to go from here. It is possible I am actually anemic or have a cardiac concern so I'm not sure whether to get a doctors letter to try and support that I truly was sick or to just leave it and solve the issue so it doesn't happen again. My frustration and sadness over this situation is really not even describable. I was mortified and angry with myself. I love my job and I would never want to jeopardize it.
