Hi
So a while back while I was in a biology lesson my teacher was talking about blood circulation around the body. Seeing blood doesn’t bother me at all but this was really making me feel uncomfortable. It got to a point where I just had my head in my hands and was breathing really fast and felt extremely lightheaded due to what he was talking about. I felt like crying because of how it felt. He then made the situation worse (as he didn’t see me freaking out) and started talking about a guy who cut through that big artery in the leg that’s really dangerous. He went into detail about the blood squirting out and all that stuff and I full on started to loose it. I felt like I was gonna be sick or pass out and I was struggling to breath properly so I was taking lots of breaths and I just remember being so distressed. It got so bad the teacher sent me out of the class room to talk to me and to check if I was ok. I can’t remember if I blacked out but I don’t think I did. This was the first time anything like this has happened to me and it hasn’t happened again after it. I never get panic attacks and I don’t have anxiety so I was wondering what this could be caused by.
Any help would be great.
