Please help me. Have a horrid phobia of needles. Am getting a blood test in 3 hours.thinking about cancelling?

Okay, I am not afraid of needles at all. I've had blood taken tons of times. I do however understand having an irrational fear. I am petrified of driving. Can you imagine how difficult it is for me to get around? Yes people make fun of me too. The only things I can tell you to do to help with the fear are to calm down, think about how millions of people have this done every day and they turn out fine. Try to control your breathing in fact concentrate on controlling your breathing. Keep your head turned away and scrunch up your face really tight. Hopefully this helps.
