Why do I think I look gay in most pictures now ?. My mind is like how didn't I see this 😔

So i started to feel like a lesbian again and that i have to be one. I dont want to be one. I just dont. But being straight feel like a lie now. I question my whole life, my feelings and everything. The biggest indicator of this must be that i will be slowly 21 year old and ive never dated anyone and i dont really find anyone attractive and i dont even know if i truly was attracted to someone and im scared of relationships i might have trauma or have anxious avoidant attachment. Help me. I do feel lost. Really lost. I dont know who am I anymore. I feel like that i must have been gay my whole life now. I feel like an alien. I sometimes feel like 2 people are living inside of me.😞😞😞

Like I can’t think straight. This is making me doubt everything I’ve thought about myself and even makes me feel like I like the thoughts when I know I don’t. Like I would be less anxious at a time while I still have the thoughts and my mind would go “oh so you like it you must be gay” or the other one where I’m not anxious and I think of my attraction for girls that I’ve had my whole life and my mind goes “see now you’re not into them you’re gay” like it’s so stupid but so effective. I clearly remember being into girls my whole life but my mind is making me believe that all these attractions and feelings for women were all fake or “a thing of the past”. But I can still get aroused by women but I have this weird anxiety going on which brings these sensations/feelings and it’s so weird. Today I’ve spent my whole day thinking about it like I’ve been doing for 5 months now. I know that this aint normal but my mind just won’t let me live in peace. I never cared about my sexuality cuz I simply liked women my whole life but now my sexuality is a fundamental philosophy. I hate this.

The thoughts are real? I have so ocd I really think I’m gay.
