How to get rid of fear of needles?

I really, truly hate needles. Its not the pain, but its just seeing them and knowing what the doctors going to do with them. I have panic attacks and anxiety at the doctors. I really need help because I have to get vaccines to go back to school in September. Closing my eyes doesn't work, I usually think it might, then I start fighting, crying and my blood pressure skyrockets! I do need help because my doctor says if I don't calm down, I could have a heart attack. The last time I got blood drawn they brought in 2 nurses to hold me down.
