Human Brain's reaction to Scary Stuff

[Potato]

I still can't over get the fear of broken bones or breaking my bones. It's been a fear I've had for a while, but I think it was re-triggered in a way earlier this week during a slide show on bone fractures in Health. I had to go to the nurses' office, I was feeling so lightheaded, it's just, it drives me crazy and makes me want to drill my ears or scratch out my eyes whenever I encounter something like that. Another of my fears is I can't stand needles. Despite knowing it hurts less than most of the pricks I tend to though through almost everyday, the thought of a small metallic needle breaching my skin is a big no-no to me.
