Is anyone else extremely squemish?

I hate it! When I am extremely fatigued which is most of the time I am really squemish. At one point in my  life I was going to be a nurse or EMT. Now I can't even hear about bones, about injuries or watch certain things. I even start to get grossed out at my body. For example tonight my husband told me about his supervisor's injury. I asked him to please stop. He continued because he doesn't understand this nor do I.  Currently I am still grossed out and thinking about my veins, etc.
