Is it possible for ocd to become real ?

How long did it take to make this? And is it actually possible?

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.

i have been diagnosed with OCD & generalized anxiety disorder. for some reason, i’ve been very hyper aware of everything. like the way i talk, the way i see the world, how certain things sound/look/feel, and it’s very distressing. i feel like the hyper awareness makes me afraid of things? like for some reason, my mind attached to cartoons, and i was hyperfocusing on it, and got extremely scared, like scared of the cartoon for no reason? i’ve done this a lot, and i get scared i have psychosis or schizophrenia, or something that makes you afraid of things for no unknown reason. i feel so scared that this is my new normal…. im heartbroken. so many what if’s. did i just ruin my own life?? 💔
