Some suggestions, please, for cleaning up a VERY messy room

My room is an awful mess...and I live in ONE rented room! So I need to clean it up and soon. I have a lot of trash around, a lot of clutter. And a lot of old empty wine bottles to put out into our recycle bin. When I get the trash and junk out, I will hire someone to sweep and wash my floor.

Anyone here ever deal with this kind of problem? I can use some suggestions and some encouragement. If I can't get it to look better, I could get thrown out of here. I like it here and don't want that to happen. Also, looking at my room is demoralizing. It's contributing to my current state of depression. I am 75 years old and arthritic so doing anything is hard most days.
