Worrying until you are sick at your stomach and thinking about covering up an unfinished cover-up is not normal or healthy,. That level of anxiety is very worrying, and it suggests to me there is an issue. This person says they have other tattoos, but it might be one tiny one somewhere. It doesn't mean they are equipped to handle an enormous tattoo on their arm. Any attempt to cover that up again will drive this person around the twist because it will not look better.
So thanks for sharing your thoughts, but I stand by my comment.
