Grew up with a conspiracy theorist?

Ever since I was little,I've been hearing about conspiracies from my father.When I was six,he started talking to me about the government and secret societies.He has these huge beliefs about reptiles,secrets,aliens reprogramming us,ect.I'm a teenager now and know they're not true,but it's been so long and he's been obsessed practically his whole life.I know he's delusional,but it's so difficult escaping believing them now.I hate living like this.Can a psychologist help me in this?I don't really speak to my father anymore,but the thoughts are still there.No kid wants to think about blood rituals that aren't even happening.
