I can't believe I did this to myself. I hate my new tattoo
Oh that's no good. Why do you hate it?
I did this tattoo myself and I did a bad job.
If you are unhappy with that tattoo then you might want to think about a coverup job. There is also always the chance of having it laser removed.
It would look better if I get a coverup.
I think you should go for a coverup. You'll be able to pick a nice design that will make you feel better about the tattoo.
