Finished the Final Harry Potter book!!!!!!

Oh my GOD!!! I just finished the last harry potter book and I thought it was CRZY. It made me really sad at some times but I won't say anything because I do not want to give anything away to any buddy who hasn't finshed the book yet. Anyways so did anyones theories come true in the new book or were you dreadfully wrong. lol. See ya all you HP fans.
