I have similar stuff going on. I know that I've had gender dysphoria my whole life, long before I even had a framework for 'gender identity'. But I have regular OCD and it messes with me all the time. It's not even about 'whether or not I'm trans' (because I know I'm at the very least nonbinary, and definitely not the gender I was assigned at birth) but it's more about control, and perfectionism, and just my brain throwing things into the mix that have no business being there, like the idea that I don't really know myself, that there are huge horrendous parts of me I've never noticed that are rising to the surface, that sort of thing. Most of the time I'm fine but when I'm symptomatic with my OCD (like I am right now) it all becomes too much to handle.
