Ok this is a somewhat personal post but I need some guidance...

I have a blood phobia, I have been known to pass out at the site of blood and at times I feel that if I don't walk away from a conversation about an injury that I could pass out at the thought of it. It makes me crazy, its frustrating and it scares me. I'm afraid that if something would happen to my hubby when we're out on the trail that I would be absolutely worthless. When it happens its not as if I'm thinking Oh my gosh I can't handle this, it just happens. Does anyone else on here have a problem like this or does anyone know any kind of psychotherapy <img src="/forums/images/graemlins/crazy.gif" alt="" /> that helps or anyone that has successfully overcome this...I'm desperate, I'm tired of feeling mentally weak. I consider myself strong emotionally in every other aspect but I just can't shake this and I've been this way as long as I can remember.
