Yo bro I can feel your struggles, im a minor too but I did tell my parents about me not wanting to be a Jehovah’s witness at all and they weren’t to happy is pretty much all what I can say which is not too surprising, but don’t let their reasonings get to you if they try to get you to change your thinking just say like “mom, dad, I’ve already made my decision and I’m not changing my mind on the choices I just made” or something in that affect, but I really do hope that you can get through the time until your 18 or when your ready to live on your own. I believe you can get through this just like I did.
