I’m being micromanaged and I’m struggling

I have adhd and probably autism too (probably). I'm working on a project and my boss is micromanaging me. He reworks my work and, when I ask if I could have done something different, he tells me I did a great job. When I try to run a meeting, he takes over. He gives vague instructions but then expects something insanely specific. He doesn't really accept anyone's way of doing things but his own. I'm meant to be leading a few things but at this point I feel useless and powerless. He's pretty much admitted he knows he's like this so I don't think he'll change.

I'm really not good at conflict and I already feel myself shutting down more and more in the workplace. I think I'll be expected to say something (if I want to do anything about it) but it's really HARD. (Ps I'm not out with my adhd at work).

I want to leave but it's really hard to find a new job too.

My soul feels absolutely destroyed... I'm absolutely exhausted and drained.
