I am an ER nurse and I had one incident where I felt like I was going to pass out and now since then almost every time I am assisting in a bloody or invasive procedure or even cleaning out a large open wound I get nervous I'm going to have that feeling again and I usually will get light headed, feel hot and sweaty and heart will feel like it's pounding. I have never actually passed out so don't know if this is just anxiety or if I will eventually pass out. Any suggestions of how to get over this? Have you heard of anyone doing hypnotherapy for situations like this?
