The hole in your belly button will heal up and close. Just be thankful you weren't manipulated into permanent decisions like cutting off healthy body parts. I think the acid I took in the 70s kicks back in sometimes.
I thank God every day my parents stood behind me when I was on the internet as a child, and also that I did not get some shitty band tattoo. Also grateful that I did not hang around anyone who abused prescription medicine, bc that is half as bad as scooping out your thighmeat to make a useless dong flap.
