Everything takes time. You have gotta lose your pride; you have gotta lose your mind just to find your peace of mind. You have got to trust the signs.
Everything will turn out fine
So I saw a post from you and like it got me thinking about Ozai sending Zuko after the avatar and Zuko's surprise at the age Aang was! Like they were probably thinking the Avatar was a fully fledged adult who had already mastered the elements?!? So that leads me to believe that Ozai sent him after the avatar knowing that his CHILD would possibly fight against an fully fledged Avatar and probably didn't expect him to live. For all he knew he was sending his son to his death and he didn't care.
