Am having my first blood test tomorrow. Hate and am scared of needles. Having a blood test is my biggest fear?

i know one guy old enough who loves action movies where all u can see is blood and dead bodies but when it comes to a needle he turns his eyes. and i know a little cute girl, 4 years old, who loves to go to the doctor and love having injections. don't be afraid it is not painfull. especially for blood test.
