There's a fanfiction where Aang is heartbroken after a big battle. His friends don't fully understand his pain at first. The story focuses on how he copes with this heartbreak alone and then gradually opens up. It shows his growth from the experience. I can't recall the exact title though.
Self - discovery is also a theme. Through the heartbreak, Aang has to reevaluate who he is and what he wants. He may question his purpose as the Avatar or his ability to love. This can lead to him growing and changing in unexpected ways in the fanfiction.
One possible reason could be unrequited love. Maybe he has strong feelings for a character who doesn't feel the same way about him. For example, if he has a crush on Katara but she falls for someone else. Another reason might be the loss of a close friend. If Zuko or Toph were to sacrifice themselves to save the world, Aang would be heartbroken as they are his dear friends. Also, if he fails in his duty as the Avatar to protect the world from a great threat, he could feel a deep sense of heartbreak and failure.
