Our parents are not supposed to raise us to become mini versions of them nor should they expect us to be completely aligned in all matters in life -serious or frivolous-. Do not feel guilty over this. If your parents are the amazing parents you are describing them to be, they should understand. If not, I'm sorry but this is not something you need to beat yourself up for. If I were you, I would seek professional assistance by a mental health professional in order to guide me through this period of my life. It is a different thing to love your parents and another one to seek their approval.

All the best.
