HOCD or what?

I could not be more thankful to find that I am not alone on this. I guess I will start from the beginning. My symptoms didn't start to happen until I started trying LSD frequently this last summer. It was weird, every once in a while during the trips I would think "no one thinks your gay calm down" and though I would regain control, I have no idea why I started to think of it all the time! I have always been attracted to women and not once have I fantasized about the same sex. I remember my first girlfriend and the feelings that came with that and it was wonderful. Especially later in life when I started to experience the more physical aspect of the relationship. Though I have been rather lonely over the past year and have been striking out with women which is upsetting me. But the last time I ate LSD about 1 month ago something snapped in my head that I felt like everyone thought I was gay and ever since I haven't been the same. I couldn't even speak that whole time yet I could hear everything around me. What made it worse was that my friends starting talking about me and saying is he gay and I wanted to respond but I was in like panic mode and couldn't speak. I'm trying to hang out with my friends now but I feel generally uncomfortable, especially thinking of that they think i'm gay, and even hearing the word gay gives me anxiety. What's even worse is that now it seems that everyone thinks i'm gay and they are all treating me differently. It is really killing me right now because I just want to know so this feeling go away. I keep having this battle with myself, like I know deep down I know i'm not gay but my brain keeps telling me I am and I feel like I should just agree with it so i'm not so nervous all the time. I just want to be happy. The thought of being with another man disgusts me and I still get hard to women and thoughts of previous sexual experiences I had with women. I don't understand how this started to happen because I used not care about what people thought of me and I never had these thoughts occur and I was comfortable in my own skin but now it's so bad that I have to make sure I don't think i'm walking gay or dressing gay. It's hard to explain. I got prescribed to zoloft and ativan and i'm seeing a therapist for my social anxiety but I haven't explained this OCD feeling I have because i'm not sure if he'll understand. I think a cognitive behavioral therapist would be best. Any input on what helped and what didn't would be awesome and overall if you got rid of this obsession how you did it?
