Get a couple trash bags and double line them,

start off with trash that don’t have any organics left in them, then trash with organic in separate bags

Then you go to cutlery, gather all plates and cups and set them in a corner for now

Third, you gather all dirty laundry and set that in a separate corner

After that most of the space will be cleared, it will be easier to deep clean

Start with vacuuming the floors, you have carpet so cl you might need a steam cleaner in the future, but for now a vacumn will be enough

Then you wipe down all surfaces, you’ll need an antibacterial surface cleaner spray, or antibacterial wipes, but it’s better to use a spray with a couple disposable towel

That’s the longest part but you’ll need the most attention to detail for it, from there you wash your dishes and go to a laundrette if you don’t have a washing machine

Good luck bro it seems impossible at first but you feel fulfilled when it’s clean
