Ameen,ameen,ameen...He is in my prayers akhi fiAllah, Allah make him an understanding father and a kind one. Ameen
p.s. If your dad is a senior citizen akhi, well, we all need to expect these kind of behaviors from those who are aging and we need to be kind towards them...because they get angry, frastrated and blame alot,
IT'S NOT BECAUSE THEY HATE YOU OR WANT TO HURT YOU but because that is just the way they've become as they aged. so, akhi bear with him as much as you can and inshaAllah, you will be rewarded greatly by Allah the most merciful.
brother, I thought I should share this verses with you

since, they talk about parents and aging
وَقَضىٰ رَبُّكَ أَلّا تَعبُدوا إِلّا إِيّاهُ وَبِالوٰلِدَينِ إِحسٰنًا ۚ إِمّا يَبلُغَنَّ عِندَكَ الكِبَرَ أَحَدُهُما أَو كِلاهُما فَلا تَقُل لَهُما أُفٍّ وَلا تَنهَرهُما وَقُل لَهُما قَولًا كَريمًا ﴿٢٣(23) Your Lord has ordered you to worship none except Him, and to be good to your parents. If either or both of them attain old age with you, do not say: "Fie on you", nor rebuke them, but speak to them with words of respect.
وَاخفِض لَهُما جَناحَ الذُّلِّ مِنَ الرَّحمَةِ وَقُل رَبِّ ارحَمهُما كَما رَبَّيانى صَغيرًا ﴿٢٤(24) And lower to them the wing of humbleness out of mercy and say: 'My Lord, be merciful to them, as they raised me since I was little.'
رَبُّكُم أَعلَمُ بِما فى نُفوسِكُم ۚ إِن تَكونوا صٰلِحينَ فَإِنَّهُ كانَ لِلأَوّٰبينَ غَفورًا ﴿٢٥(25) Your Lord knows very well what is in your hearts. If you are good, He is forgiving to those who are penitent.
Assalamu alaikum,
Allah hafiz now and always
