The fortune teller said that I was sent to this world by Guanyin.

Guanyin is a Buddhist bodhisattva, and Buddhists are forbidden to tell fortune. If you believe in Buddhism, ignore him. According to Buddhism, you are you because of the cycle of karma, even the Buddha can't compare with karma, let alone the bodhisattva, so the bodhisattva has no ability to reincarnate you, and she made everything herself. Don't listen to nonsense.
