Nah, its no big deal. :P
I get them all the time. I used to be a bit squemish, not anymore. XD I get bloodwork at least once a month, IVs up to twice a month. (I used to get them once a week for almost a year, when my lupus was really bad). I've even had a needle shoved into my hip (twice) and one up my spine (twice).
I'd hold someones hand if anyone goes with you, even a nurse is better than nothing :P. Look away from the spot you're getting. DON'T close your eyes, it makes any dizziness you may feel (from being so freaked out - I get dizzy when I'm nervous) TEN TIMES WORSE. Take slow, deep breathes. Concentrate on a special word. Like Betta. Breathe in and think "Betta" breath out and think "betta". It helps a lot to focus on something else.
Good luck! Maybe buy yourself a little reward after ;) -coughbettacough-
