Is it possible for ocd to become real ?

I have been having these fears about developing schizophrenia, it reached a point where i am starting to almost hear things or the smallest sounds and my mind tells me you're schizophrenic, and i feel this weird sensations in my ear as if someone is whispering yet i can barely hear them, the thing is i am not diagnosed yet because i never work with an OCD therapist but i study psychology so i just used what i learnt to give a meaning to my suffering, many themes of this fear have been happening before and this schizophrenia fear is the last one. I want to know what advice you can give me or ways to make my brain calm down a little bit, i also don't have and can't afford a therapist that's why i am here in the first place I also want to know more informations or experiences with this theme if anyone habe experienced it and what helped you with it I remember feeling better for a while but than i collapsed back, but i am hoping to get better soon too or anytime in the future, I don't want reassurance so make sure you be as real as you can, and thanks 🙏🏻

With ocd can the thoughts themselves feel entirely true???? Or is it just the narrative around the thought that feels true/real?

How can i 100 percent ocd is lie? How does ocd always lie?
