Dear Guinevere: I had to give one of my kitties daily shots and I was very frightened especially since I had never used a needle and had to get it in a specific place and not miss and hope my sweet kitty would stay calm. I had someone with me for the first few times who knew about these things. It gave me confidence to have a coach and someone there just in case. I got pretty good at it by myself. Whew. Is there someone who could guide you in the beginning? I had a friend who was a vet tech, anyone with regular experience using a needle. That gave me confidence. I hope it works out for you. I am a worry wort also. Keep us posted.
