I'm very late to this interesting and somewhat confusing thread. I am not sure I have much to add to what others have suggested. I thought LisaP's advice was clear and extremely practical. (In fact, I think I gave you similar advice in an earlier thread, and it's certainly consistent with Angie's suggestions).
Someone upthread mused that Angie's suggestions re closet cleanouts being a day long process don't work well for hoarders. Maybe. It's true that most of her clients probably edit their closets regularly. (At least if they work with her regularly, they do!) But there is a first time for everyone and knowing Angie, I know what she would do. She's highly decisive and would not dither. OUT out OUT would be what she'd say to most anything that had been there longer than 3 years or anything that didn't fit, wasn't being worn, etc.
Anyway, as someone who, like you, came to the forum following weight loss and in the midst of a lifestyle change, what I did -- practically speaking -- is what Vix advises.
"I'm advising you pull together 10 or so wear-right-now outfits you like so you have something to wear as you ponder and ideally shop for core wardrobe items.
Then I'd encourage you to pack up the remaining items. If I were your friend I'd try to get you to donate them -- a fresh start given your large weight loss and life changes! But put them out of sight at the least."
In my own case, I did exactly that, and got rid of almost all my old clothes except the bare necessities for a few outfits. I then built from the ground up, focusing on my new weight/ shape and my new needs.
I did try to alter a few favourites, but without much luck.
How did I begin? First, a friend or two donated a few items in my new size. (A little black dress, a top or two. I even got donations from generous forum members!)
I then shopped mainly at consignment and thrift and discount stores for my first year (when my income was very low). I ended up ditching most of those items eventually when my weight stabilized and my income increased, but shopping this way helped me experiment with different styles and cuts and colours.
After my first year, I had developed a slightly more secure sense of what worked for me and I began to stock my closet with new clothes. It took time. I joined the forum in 2011 and it was really not until 2013 until I felt like I was starting to get a handle on my personal style (which I still consider a work-in-progress) or until 2014 or 2015 when I started to feel that my closet was the right size and highly workable for my 4 season climate. That is, until then, I was often caught without an appropriate outfit for regular or semi-regular activities and had to improvise in a way that felt awkward. Developing a personal style and a wardrobe that works is a marathon, not a sprint.
You mention that you are not visual and this, as Rachy said, is going to make defining your style much more difficult. But if you are not visual, perhaps you can base your style on how things feel vs. how they look.
Several long-time forum members here are blind or low-vision. For them, the feel of a garment on their body is especially important and they have refined this to a fine art. Together with friends, forum members, or stylists, they determined a very defined colour palette to work with (since they can't see what colours flatter them). They then figured out a few key silhouettes that work for their figure type/ body type. And from that point in, it's a question of how it feels.
I wonder if focusing on feel might work better for you than collecting images, if you find imagery confusing?
