Is it permissible for a girl to show sadness and stop speaking to her parents when she feels mistreated and does not receive the desired affection?

It is obligatory to be dutiful to one's parents, and forsaking them or turning away from them is a grave sin and an unlawful act of disobedience, because Allah has commanded kindness towards them and prohibited cutting off family ties. It is obligatory to repent from that and return to treating them well and accompanying them with kindness, even if they have wronged.
