Personally a big part of being able to really DO this is your commitment to... well, doing this. If you're not committed--if you're not willing to just plow forward and push discouragement aside, it might not work out for you. Your shop is still VERY new, your inventory is still fairly small (lots of people say to shoot for 100 items in inventory). A lot of people don't realize that selling on Etsy isn't the same as selling in a shop, a fair, a bazaar, etc--it's not instant gratification on Etsy. It's a different market and it takes time, commitment, hard work and most of all: patience. And IMHO it takes a lot more patience to make it on Etsy than it does to have a table at a bazaar. The customers come to YOU at bazaars, but on Etsy, you have to go out and bring the customers IN.
It'd be a shame for the discouragement to get the better of you! IMHO your shop is too new to even be THINKING about calling it quits. Just be patient, keep your chin up, and keep plugging away!
Wishing you luck!
