Nervous before lancing, how do I get over it?

I've got the ReliOn lancer and am using 33 gauge ReliOn lancets. (I went to Walmart...) It doesn't really hurt, but I get nervous every time I do it and then I'm really shaky afterwards. It doesn't help that my blood sugar is 290 right now...

Any tips for not getting so worried. I know lancets these days are pretty painless compared with the old days and this hurts way way less than the a1c my doctor did.
