Is it permissible for a female student to seek financial assistance from charitable organizations or teachers, given that her father is financially capable but neglects to spend on her, which causes her financial and psychological problems?

You must be dutiful to your father even if he is stingy and ill-tempered. He is not obligated to pay for your educational expenses unless they are essential. It is advisable to involve someone your father trusts to encourage him to provide for you, and to treat him well and dutifully. It is not permissible to accept aid from charities or teachers unless you inform them of the full situation and they agree, as such aid is often designated for those who have no provider. It is recommended to practice self-restraint, avoid asking for help, and strive to manage your affairs with what your father provides.
