First event, I was so excited thought my table looked good. Was not successful at all

Had my first event. I was feeling really optimistic about it. Thought I had a nice set up. It was a lot of work for me. I have fibromyalgia and a lot of pain in my hands but I love to craft. So it does take me a little more time and work. This event also had trick or treaters so I spent money on table and $20 for candy. I did not have success. Everyone just walked by not even looking. The very few who did look commented how they liked my cat earrings but nobody bought. It was really hard not to get super sad and discouraged. Not gonna lie I had to run to the bathroom a couple of times to hold back tears. I just kept thinking about all the work I had put into it for nothing. Now I have all this Halloween stuff and nobody to sell it to. My plan was to use this money to make things for my next market which is a lot bigger event and a 10x 10. Now I feel stuck and really discouraged.
