I've realized I may not have been that clear to what "the change" is exactly. It's kind of like puberty but a little different. Instead of growing gradually their body reaches its full growth within the first three months. The change starts at thirteen and ends at eighteen. Because their body has grown so rapidly their emotions and thought processes have to take longer to fully mature, thus why it takes five years. After the change a person can be completely different then before, so basically their whole personality changes. But while going though the change your mind is basically sorting through what kind of person you're going to be which causes drastic mood swings. Once you have finished your change your true colors come out. It usually goes through stages, but everyone goes through a different stage at a different time. The stages are the emotions you go through. The closer you become to the end of the change the more mood swings you'll have. I hope this helps, and sorry for any similarities it was not intended. Lots of love xoxo
