Question: What causes OCD. Nature and/or Nurture?

So basically I didn’t know till my hocd started. But looking back at my life I had ocd since I was a kid. Like 6-7 years old. First time happening I remember that when I was doing stuff many times I had to say something like a little poem in my head to stop it. Then I had this thing were if I felt my left foot touch the floor 5 times I had to do the touch the floor with my right foot too. Then I had something I guess contamination??? Basically after washing my hands I had a sensation on my hand like I could still “feel” the germs and I had to wash them again. Then I started having thoughts of my family members getting hurt. I had intrusive thoughts about me hurting my dog. Then I had this obsession that a guy who used to be in my school is looking for me to beat me up. And how it’s this obsession about my sexuality even tho I never doubted or questioned it before. Is that possible??? Like can you be born with it? I’m pretty sure both my parents have it too. At least at some level. Take my father for example he had an obsession that he was going to die the moment he turned 30.

What’s involved in this process? •demons •tyrants (actual people) •replacing hobbies with church I believe we were all born with talents, interests, I don’t think religion or spirituality should ever be a hobby or something for fun or to dive into when ur bored religion or spirituality should only be approached when needed needed crucially needed is what I’m starting to believe. That just makes sense. Why would God want us thanking him constantly when he just wants to help us and want us to know like “hey bro here if u need anything holler at me.” and like he kicks up his feet and does his own thing, like what if god is just like that and then here I am having mad anxiety that I just put Gods name I lowercase but I meant no disrespect towards god when doing that. n that’s my point again, why would the person who created me to experience feeling grass on my thighs and walking this earth to look at sunsets he creates for us each day n eat good yellow mangos n explore rainforest and ultimately “LIVE LIFE.”, of course I would assume the one who wanted us to experience life on earth for a bit would maybe perhaps be like any ordinary day and say, “make good decisions.” Before you walk out the door, like imagine the whole Bible was just those 3 factors I’ve just pointed out •live life • make good decisions •I’m here if you need me I’m really gonna create the type of God that works for me idc anymore this is really giving me so much peace Do/Did many/most people with OCD have an absent parent/abusive parent? I’m starting to think that could also be another reason why OCD is developed Is that already a proven fact? Would make lots of sense.

How do you know if it is OCD or just anxiety caused by inner conflict that needs to be resolved? Thoughts - discussions?
