I am aware of how you feel. I work a lot, preparing new stuff, taking picture, listing and then ... no sales. I am always excited and proud when I list something new but then when I see that I have no views or sales I think: ok now I stop and I am no more listing.
I am addicted to crochet or knit, my hands have to always busy so now I am stocking items but I am scared that I am not going to sell them and also my budget is limited, if I don't sell I can't buy too much supplies.
