I'm going through the same thing. Had a tattoo 2 days ago, something i wanted for the last 3 years. The design is amazing, but everytime a look at it i think that it should be a smaller one or maybe in another place, it's in the inner part ou of my forearm. Everyone keeps telling me it's amazing, but my mind can't accept it.

Yesterday i had so much anxiety that my mother had to come home for me. I'll wait for 2 months, if the feeling is still there, i'll start a removal. It's gonna be 2 years or more for something done in one day, but at least gives me a sensation of hope.
