If I could change several things, that would be on my list. I got a chest tattoo, that later became a breast tattoo. I at least wish it wasn't a walk in :)
I'd have dated Shane all of those years ago. We'd have been long broken up by now either way, but it would have let me deal with so many other things I was hiding from
Only one thing? My life is a mistake after another!
The biggest change I'd do is a bit too personal to share, but I guess that the second one would be to care about my own looks earlier than I did. Light exercise, some sport and things like this would've done so much for me around my 10s. In turn, that would've turned my whole life for better.
