You can change anything you want to change, and you can do it very fast. That's another satanic suckerpunch--that it takes years and years and eons of eternity to repent. It takes exactly as long to repent as it takes you to say, "I'll change"--and mean it. Of course there will be problems to work out and restitutions to make. You may well spend--indeed you had better spend--the rest of your life proving your repentance by its permanence. But change, growth, renewal, and repentance can come for you as instantaneously as for Alma and the sons of Mosiah.
