Tetanus and Meningoccal vaccine help!?

I'm getting a shot tomorrow and my dad told me at the very last second. I have to get these shots to attend school. I'm so scared of needles and I have tattoos to hide so I'm afraid they'll see them and tell my dad. Could i ask to get these shots nasally or somewhere else other than my arm. Do they do your shots on the opposite hand you write with? Where on your arm do they do it if i have to go through with it? I'm 16 idk if that helps but thank you so much I just need to know everything i can about these shots.
