Is a mother's obedience obligatory if disobeying her leads to a deterioration in her psychological and mental health, even if her request does not originally necessitate obedience and causes hardship to the son?

Obeying parents is obligatory in matters that benefit them and do not harm their child. If they command their child to do something that would harm him, or if they command him out of obstinacy in something that brings them no benefit, then obedience is not obligatory. What the mother commands or forbids for a valid reason, and without harm to the child, then obedience to her in that is obligatory. However, if it causes harm to the child, then obedience to her in that is not obligatory, even if disobedience results in harm due to the mother's illness. One must strive to be dutiful and please her in ways that cause no harm. But if there is no harm to the child, it seems obligatory to obey them in what they command, even if it is not originally something in which obedience is obligatory, out of consideration for the harm they may suffer due to his disobedience.
