HOCD!! Will it ever be gone forever? PLEASE HELP

Everything I do, I still think about it in the back of my mind even though I don't want to. It's so annoying. I think I couldn't have a fun life anymore if I continuously think about it like this. I couldn't imagine my life without HOCD anymore. I don't want to see a guy and feel weird anymore. I don't want to fix my mind when I see a guy and get anxious and tell myself it's HOCD and I'm gay. It's not fun at all. I couldn't go to a party with my friend and feel the same as it used to be cuz when I'm drunk, situation gets worse. I know I'm not gay. I just don't want to automatically check other dudes out.SO WILL IT EVER BE GONE LIKE WIND?

Story of me when HOCD first begun
I'm 21 years old living in Thailand. Last month I went to smoke weed in my friend's place. After I went high, I got picture of me having sex with him and It's so scary. When I'm sober, I felt really really weird and scary. And that's the beginning of it. I went home and googled about how do I know I'm gay and all the stuff. You know. It's freaking scary because everything is similar to me. What they said I don't want to tell in case you get the same sensation. I think about this all day except when I fall asleep. It consumes my mental energy. I couldn't do things as good as I used to do. My grade drops and everything got screwed up. I couldn't look my best friend in the eyes because I fear I will love him. This sucks. I spent more than 3 hours learning and searching for HOCD. I also got other symtoms as everyone else does. Checking, unwanted thought and image.

Spike can bother me less now but I still think about it 24/7. I stop PMO and it feels good because my sex drive has come back. Try it for one week without PMO. I quit smoking. Stop drinking. However, it's tired when this thought is not going away. I feel hard to breath and chest is tense and also with the stomach.

Anyone has ever experienced this HOCD and fully recovered(no thought anymore). Please tell me how you do. I beg you. Thanks
