Not being able to clean my room. (vent?)

Idk if this is the right subreddit, as I haven't been diagnosed with anything yet (though I have done extensive research for over two years.) But right now I got a burst of energy to clean my room (I never have)

I went ten minutes in before stopping because it was becoming overwhelming, and I ended up crying. I really don't know why I can't just be normal and clean like others.

Every single time I try to do this, it gets overwhelming. This time I even tried putting my hair up in a hair tie and wore shorts and a short sleeves shirt. But, still, that just made it worse.

I don't know what to do. My dad said he'd throw away everything on my floor if it isn't cleaned my tomorrow. Any tips would be greatly appreciated
