What steps do I take? I’m losing myself

I have had ocd for about 7 years and hocd has been the main theme for about 3 of those years, I have had damn near every theme in the book but this one has just been impossible to get rid of.
My hocd was never really that strong after a while because I thought sexuality can’t change and it was obvious I have been girl crazy and never liked guys

I have seen people online say they weren’t attracted to the opposite gender until their late 20s and 30s and man it’s just really messed me up cause before hearing things like that i would kinda just think it seems irrational for me to wake up when im like 32 and like guys

I always thought it was something you were born as, but with that info it sent me spiraling asking chat gpt things like “can I turn gay after puberty” and it would say yes and now its like my attraction for girls is just completely gone cause of my anxiety I don’t really get groinals or look at a dude and feel anxiety anymore it’s more a fear that I’m going to one day see a dude and just be attracted to him, while I have read up on studies and seen professionals say it’s not really supported that it’s possible for it happen just seeing people online say it happened to them has just sent me into a shell of my former self

Any help would be much appreciated
