Is the amulet placed on a girl when she is young, for fear of rape, forbidden and considered witchcraft, and if so, how can it be undone for psychological comfort?

Sorcery is one of the gravest sins, and the mother erred by going to soothsayers and sorcerers, because the Sharia has forbidden approaching them and believing them. And whoever undoes magic with similar magic has committed another sin, because that is from the work of Satan. As for undoing magic with Ruqyah, seeking refuge [with Allah], and lawful supplications, this is permissible.
