Got tattoo. Removed tattoo (laser). Tried to cover scar w/new tattoo. Removed coverup. Left with permanent scarring. Can my skin ever fully heal?

No, but... Nobody has a perfect body, Ben. You had an adventure. You had the courage to make a statement, and even if things didn't turn out as you'd hoped, your life is richer. The key to looking and feeling good is fitness. How trim and muscular your are is entirely up to you. And you've got a story to share from a time when you were younger. Be good to yourself, and best wishes.
