Seriously struggling to clean my room...

Hey all. For as long as I can remember, I've always struggled to consistently keep my room clean. I'll clean it up, but then slowly over time it gets bad again.

Right now, it's pretty bad. Lots of dust, trash, hair, clean and dirty clothes, assorted filth, etc. I just tried to start cleaning it, and I got very overwhelmed very fast. I also got super sweaty, grumpy, and overstimulated. I had to stop. I hate coming across random strands of (ironically) my own hair and it really makes my sensory issues flare up.

I live with my parents, and of course they're always on my ass about keeping it clean. They think that I do it to spite them, which is the farthest from the case. I want a clean room so badly. I just really struggle to start it, let alone finish it. My parents have this "just do it" attitude, and I've tried to explain to them how I can't even do that. I have to be in the right mindset, not be exhausted, have the motivation, etc. They still don't really understand how ADHD hinders my life, despite me being properly diagnosed by a doctor. They've also offered to help me, and I say no, because it's horribly embarrassing how bad it is, and I know the entire time they'll just chastise me.

At this point, I'm heavily considering hiring a special/professional crew. I'm just so overwhelmed, and I so desperately want to have my own personal space back that I can enjoy...

I appreciate any advice ❤️
