Will a girl be held accountable for her prayers during a period when she was unaware of the prescribed ritual bath, and how can she improve her morals and re-educate herself after the violence and indoctrination of lying she suffered in her childhood?

You must make up for the missed prayers, according to the majority of scholars, which is the more cautious approach. However, some scholars hold that it is not obligatory because you were excused due to ignorance. Seek Allah's help in striving against your lower self and purifying it, for good morals are acquired through habit and practice, as stated in the Hadith (definition): "And whoever seeks chastity, Allah will make him chaste, and whoever seeks patience, Allah will make him patient." Be keen to associate with righteous women, learn what is necessary for you regarding your religious matters, and frequently supplicate for guidance to the best of morals.
