Not to minimise what you're going through, but you've only had the tattoo for a couple of weeks so give it some time. When it comes down to it, by getting tattooed you're doing a pretty heavy thing by permanently altering the appearance of your body, your perception of yourself, people's perception of you, you're maybe coming up against taboos...it's a lot to take on, and I don't think you can really prepare yourself for it beforehand. I think it's okay to have complicated feelings towards your tattoos. But really, give it some time, and if you decide that you really can't stand being tattooed, there's a lot of really great stuff here about tattoo removal.
