It's OK Lauren! *hugs* I promise, I completely understand how you feel. I was very sick almost 5 years ago, and they needed bloodwork and also an IV to rehydrate me. No matter what I did, no matter what was said, I couldn't even let them poke the needle in me. I just couldn't. I sat in the hospital bed for almost an hour. So they finally sent me home (with much reluctance), saying I should try to drink lots of water even though I couldn't keep anything down. They needed bloodwork a week later, again, couldn't do it.
After a month I was still sick and absolutely needed to have it done to figure out the problem. They had to try multiple times to hit a vein, which was my worst fear...but. I finally managed to convince myself that it was OK by imaging the needle as something else. Rather than thinking "omg it's going into my skin omg it's going inside me" I just imagined it as if someone was punching me in the arm and making it sting. I figure, I could handle the sting of someone punching me or pinching me for ten seconds, cause it's on the outside, I'm not freaked out by something going inside. So my strategy now is look away from the needle, take a deep breath, imagine that the nurse is going to pinch my skin with her fingers for ten seconds or so, and just kind of let that wash over me. Needles are still difficult, but I make it through.
