first of all that tattoo is fuckin awesome. sorry you are experiencing that though. while not having full blown panic attacks, I’ve had similar experiences with bigger pieces. i’ve never been one of those people that gets a tattoo and is immediately so psyched and wow’d by it, it takes me some time to love it, hate it, and get used to it. i think the risk, feelings, and change process is part of the art in a lot of ways. i would try to give it some time. everything in life is impermanent, including our bodies, minds, feelings, and thoughts. hang in there. and again that tattoo rocks.
