At the bottom is a link to one site with good information about burn out. However you need to go to your stress debrief team and see who the mental health professional is. Sounds to me like you have more than just an incident or just school. In emergency care we often get caught up in helping everyone else except ourselves and overtime it takes it toll. It does not matter if you have been doing this for 2 days, 2 months, 2 years or 20 years it can catch up with you if you don't take care of your self. We had one EMT that went off the deep end on a routine transfer. Come to find out the lady looked like her Mom who had SERIOUSLY abused her when she was a child and seeing this lady opened up the gate for her that she has never been able to close.
Find a good counselor I did not use the one our system provided, I found one that specialized in emergency workers while she is not one of us she knows how to help. I just felt the one we had with our unit was too much of a talker and I did not want everyone thinking I was weak, or could not handle the job. Never mind that in our small community I picked up 9 patients in 2 weeks that all died and the oldest was 12 and my best friends son. I just could not figure out why I was burnt out. It took about 2 years to get myself back to feeling good and like a productive member of society. If your proctor does not understand this then maybe it is time for him to do something different. when we loose the caring about each other or the students that are going to replace those of us who have been at it for ever then it is time for us to move along. let me know if this web site helps. I have all the papers that show this stuff but can not find it on line.
