You sound overwhelmed by what you see in this picture. Don't be! You can get this sorted
Set a timer for 15 minutes, and:
Take the lovers off that shelf and display them somewhere where you can admire their beauty.
That frees up a shelf. Put your pans there for the time being
And then I would say take some of the suggestions here, about grouping like with like, and move from there.
If you really want to get rid of stuff, but don't know where to start, borrow a page from Thistle and Claire and some of the other ladies: Thistle is always talking about whether an item makes her feel like a '10' on a happiness scale when she wears it. And Claire has an 'only the best in my closet' attitude. So go through your stuff, item by item, 15 minutes at a time. Does it make you feel like a '10' when you wear it? Is the condition of the item a '10'? I would say only 9's and 10's should be in your closet.
When that timer goes off, go do something else for 15 minutes, and come back to the closet later, so you don't get overwhelmed. Take breaks, do other things, let your mind clear a little.
You don't have to get everything done today. You could work at this 15 minutes a day, and be astonished at where you are in two weeks. So you can get a head start on when Angie comes to visit
(And omg, Caro, I LOVE that video! Sipping coffee on a break while I watch some of the others)
