Getting blood drawn tomorrow, Freaking out, Can anyone help? Please?

So I have to get blood drawn for an allergy test tomorrow. I'm really scared, I'm sick to my stomach and about to cry. I've had IV's before but they were really both bad experiences. My first allergy test (Five years ago) was in my elbow pit, and the nurse twirled the needle around to find a vein, literally TWIRLED the needle. About three years ago I had to get a tube down my throat so again, I had an IV, He gave me a shot in the underside of my wrist to numb it but didn't wait for it to numb and once again, twirled the needle around. I'm petrified of needles (shot wise) and I need help. Is there any way to make it hurt less? Any thing I can do to calm down? Please Please Please help me.
