I need help please regarding religion..

M • In a relationship for 2 years❤️
Im in my late teens and my parents are very religious christians. We changed fellowships recently but i still dont feel any spiritual presence whatsover. When i tell my dad that i dont want to go and i stay in bed he starts pulling my hair which really hurts. I feel that one shouldnt be forced to be religious, i tried praying and stuff but i feel nothing. Can you please tell me what i should do or what i can tell my parents?
