TheDorkingGlasses and Ya Boi Guzman are absolutely correct. Couldn't have said it better myself, so I won't.
You're old enough to get one but you have to have a notorized paper signed by your guardian saying that you can get it, you can get the exact paper from Enigma and get it notarized at any UPS store or bank. And the price changes based on color, size, and where at on the body so you want to go in and ask for an estimate after giving them exacts with what you want. And it'll get better.
There's a section on their website about minors getting tattoos. Have a look there. Sorry for your loss hun.
