Jehovah's witness: what do i do?

well all throughout my life i have had this religion involved in my life even though i didn't want it to be. i have bashed this religion to no end but things have changed. i have started to go to my grandparents congregation and have enjoyed it. in the last few years i have gone through much emotional trauma in my life and i felt like i needed more to live for. i guess deep down i already new that Jehovah was the true god. but my question is what do i do about my family. i'm only 13 and i still live with my parents and my dad really doesn't want me to follow this religion but he hasn't actually voiced his opinion. but my mom is absolutely AGAINST it. she was borne and raised a Jehovah witness and she already said that she wouldn't allow me to follow this practice. i really need advise because i don't want to stop going, it's a home away from my dysfunctional home and i have known the people who are there since i was a baby. what do i do about my family and there different views
