For myself, at 19 I stubbornly believed that my judgement was the best judgement. I felt the same way at 16, too. I had to get to about 25 or 26 to realize that I was mostly a hormonal idiot. Every 10 years I look back and go "huh, that was naive".
I just hope all of this works out for the OP. As a father of a daughter, it feels scary, but my fear doesn't help anyone.
Right, the Texas tattoo would be my first priority, too ๐
