All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
That a person may envy himself or affect himself with the evil eye is possible; Ibn al-Qayyim said, “A man may affect himself with the evil eye.”
The treatment for this is to supplicate Allah to bless everything he likes in himself, or his wealth, or anything else.
The Prophet said, “If anyone of you sees in himself, or his wealth, or his brother what he likes, then let him supplicate Allah to bless it for him as the evil eye is true.” [Ibn as-Sunni in Aa'maal Al-Yawm wal-Laylah - Al-Albaani graded it saheeh (sound)]
Allah knows best.
