What was I made for? (Optimus prime fanfic)

Emma Walsh was abandoned by her father and when Optimus first got on Earth he found her hurt and injured. Emma couldn't speak because of a mental illness which consumed her voice.

Optimus took the child in and protected her with his spark. He was kind of rough with her but that was to protect her. He was able to help her find her father again but her father didn't want her back.

What will happen when she attempts to kill herself?
