I'm 53 years old and I still don't like needles. I used to get all sweaty and felt like my heart was going to beat right out of my chest.
All I do now, is just take a deep breath, sit down, close my eyes and picture my furkids in my head doing something silly. Believe me it helps. Well it does me anyway.

Maybe you can do something like that to take away the anxiety and from what my sons told me when they had to have their shots, it didn't hurt one bit.

Good luck my dear.
