chickened out of my tattoo

I'm so pissed at myself. I had this tattoo picked it for months and went to get it today. I forgot my anxiety medicine so I was already on edge then the people were rude to me and my friend. She kept saying it's so small and simple just pay for another one and we can add this one for like $5. I feel so silly and immature. Should I go back or pick a different shop?
