Hi Alia3
I'd suggest you discuss, very very honestly, with a psychiatric doctor (not a therapist or general practitioner), these symptoms. My house gets chaotic extremely quickly due to a variety of issues I have, but it's mostly an issue I have called, "Didn't pick it up disorder."

!
In other words I have plenty of reasons for things getting out of place and not getting started recreating order, but it does come down to having motivation one way or another.
Maybe this will help. I have a variety of related anxiety symptoms. One reason I say, "Get thee to a doctor," is that I have physical symptoms (panic attack) that no amount of willpower can overcome.
One trigger is a big mess that I don't know how to begin to tackle. I can find something like this around my house any day of the week. It's not the floor here and it's not just me. Any horizontal surface is a candidate to catch any random object. From literally anywhere.
This is a farm. So when I say anywhere, I'm saying it might be from the barn 200 yards away. And outside. Outside is very scary. Heck, there are days when across the house is scary.
Now, Sam, my dog, can help with going to the barn. Between him and pilates, I'm hoping to decrease my spatial confusion.
In the house I still have a tendency to get "lost." This is where my anxiety starts to rise. I know a big pile of stuff from everywhere is going to cause me to get lost. I have to remember where each thing goes. Sometimes there are things that literally never had a belonging place. That's another decision that has to be made.
So a couple years ago I changed the game in a couple ways:
First, if I'm alone, I "declare war" on a certain type of item. Stuff That Goes in The Bathroom. Stuff That Goes In The Dog Cabinet. Dirty Dishes. Unopened Mail. I give myself a vacation from everything else! Sometimes that motivates me to do a couple other things as long as I'm at it, maybe clear a whole small space.
Second, I draft help. This is easy for me, because my husband and I made help, though it took a few years to grow them and train them. I stand by the space, pick up a number of items going to the same place, hand them to a child, and say, "Bathroom."
This method is adaptable. I did it this way before the help grew up. It takes a little more resolve though. I got a box, pictured a location, and started sifting through the pile, trying VERY HARD not to lose sight of the picture in my head of the bathroom (yes, I'm autistic). When I had a reasonable amount of stuff collected, I walked though the house saying, "bathroom, bathroom, bathroom." I did this until my head felt close to exploding, or I was done.
Again, I never try to do more than one surface at a time. My mom cleans the entire house in a couple hours. Two or three times a week. Whatever. Maybe I'll pass those genetics on to my sons' daughters.
It's the floor in your case. If I were you, I'd break it down, by sitting on the floor. Now you are eye level with your "nemesis."

If you watch TV, just clear out what's between you and the TV and enjoy your new space.
If you get a dog, you'll need plenty of floor space to romp on the floor with the dog. A lot of my friends who live alone with their dogs, actually save money by having very little furniture, and simply living Asian style.
If you took up something like yoga or pilates to help with spatial relations you'll need more room for that, too. Do you see where this is going?

I really, really understand where you are with this! I hope you can work it out. I truly do live this misery also, but I can tell you it's possible to overcome - for me it was breaking out of the box just a teeny bit at a time.

<--- I think that's a hug smiley but possibly the girl is making a rude gesture?

I'm assuming not though since this is a PG board.
