How can I deal with my father who opposes me, despite my care for him and bearing the costs of his treatment, and with my mother's and siblings' disregard for my suffering, taking into account the verses and hadiths that urge honoring one's parents?

Firstly: supplicate for your father, asking for his guidance and healing. Inform your family of what your father did to prevent it from happening again. Wear modest clothing and avoid being alone with him.

Secondly: filial piety is one of the greatest righteous deeds, and your financial support for your family is one of the most rewarding charities. Therefore, continue to do good for them.

Thirdly: overcome introversion and irritability. Initiate conversations with your siblings in a friendly and gentle manner, and seek help through patience and prayer.

Fourthly: This worldly life is a realm of trials, and patience is one of the greatest blessings. It can be acquired through habituation. Reflect on the stories of those who were patient.

Fifthly: True beauty is the beauty of the soul, noble character, and obedience to Allah, not physical beauty. For Allah looks at hearts and deeds.
