Why do I feel fully convinced of my theme 😞

I’ve had different themes of ocd throughout my life. Can they all differ such as how the thoughts may present? Currently my thoughts feel so true immediately (like they genuinely feel like what I think) but in the last theme I feel like it may have been more of a “what if I think this” type of situation

Is it normal for this theme to legit make you feel like you’re the opposite gender and that’s what you want to be and it’s very convincing? And you just keep getting images and scenarios in ur head of you transitioning and actually going through with it? This is sooo scary and i don’t feel like myself at all anymore. It’s making me not feel like a woman or myself of how I’ve always been my whole life. I’m really nervous and scared, it’s really make me feel like this is my true feelings/ self ): it’s causing me to feel weird k. My own body and feel weird about my body parts. Like my brain is literally thinking as a trans person would feel or think like wtf??? Is this normal?!? Pls someone let me know. & and it’s making me feel like I’m attracted to woman all the sudden and i keep getting flashes of that in my head. I’m in a relationship and im scared this is gonna ruin things bc the way this theme is making me feel and my body. Ugh ihml, need some advice. Has anyone experienced exactly this??

Usually my thoughts go from statements, which I fight all the time, to doubts like “do I” or “i don’t know” but I don’t fight this. I’m not sure if this is progress or it’s the truth. Anyone else feel like this?
