So I accidentally sold all my stuff on accident

So I went to a merchant and typed out “sell all my gear that I’m currently not wearing.” Instead of selling all my unused armor and gauntlets, the AI just sold EVERYTHING in my inventory. So I went and bought back all the important things I wanted to keep. No problem right? Nope, after I got the prompt that I did buy back those items, and the coins I spent got subtracted from my coin stash. My item inventory is still empty! So hear I am DEEP in my story, with an empty inventory.

How can I get it all back?
