Congratulations on the re-opening of your shop. The first hurdle is to get your items found and viewed. Your tags look ok but your titles need to describe the item in the first four words. You do not need to include 'vintage' in these four words. For example, your 'Vintage Knee High Brown Leather Boots ladies size 7', would be better described as 'Ladies Brown leather Boots - Knee High Size 7'.
Search engines will read part or all of multi-word tags but cannot add tags together. Your tags 'Brown', 'Knee high' and 'Size 7' are wasted. I would suggest changing these to 'Brown Leather Boots', 'Knee High Boots' and 'Ladies Size 7 Boots'.
You need to think "What would I type into the search bar if I was looking for one of my items?"
Also important is to keep adding new listings.
Hope your shop does well, and as for 'letting go', just think of all those things you can replace sold items with.
