What @Hogrider said. If someone says they can do it "cheap," run a mile. Quality tattoos aren't cheap. Also, not every tattoo artist will be comfortable tattooing scar tissue. Check around and ask a lot of questions if you find someone.
How dare you? Really? Hahaha. You came here asking a completely obsessive question AFTER you got tattooed. That is obsessive behavior. We see it here A LOT.
As for help to get over it, we can't help you with that. It's flash. It's fine. Just enjoy it.
It's a pair of dice. It's basically flash. Don't worry about it.
Also, why did you get a tattoo on your hand? You appear to have very few tattoos otherwise. Just curious.
Things happen. Hassling the artist isn't going to make him or her in a huge hurry to get back to you. Just leave it. Let them get well. There are lots of bugs going around at the moment.
Also, they did YOU a favor by not making you sick. So calm down.
