what does Jocasta do as a result of her realization of the truth? can you give me soures?

Jocasta went into the palace, went straight to her bedroom and slammed the door, tearing her hair with her fingers. There she cried out to Laius and bemoaned the tragedy of her son/husband. Oedipus, bursting into the palace and demanding a sword, found that Jocasta had hanged herself.
