My first time with insulin was so funny (looking back) I simply couldn't do it even though I am not bothered by needles. I asked Dh to do it and well he jabbed me so hard I bled I said a few nasty words and sat on the bed crying (ps it didn't hurt at all)

In the end i took a deep breath and in it went. no problem what so ever. I have had GD with all my pregnancies and on insulin with the last 3. I actually found the needle in the finger hurt so much as the weeks went on..

Good Luck. I promise it isn't as bad as what you are thinking
