Need an honest opinion: Is it worth it to try to continue?

[Calicos-Curios]

I've had my shopify store for about 5 months and only made about 20 sales, a good deal of which are from family/friends, and a reddit post that just happened to gain some popularity. I have no clue if I'm doing well or not. It's been really draining pouring so much time and effort into my store, and not feeling like I'm getting any return. 

I'd appreciate some honest opinions and hearing about other people's experience. 

My store is www.calicosandcurios.com 

Just for reference, most of my traffic has come from FB ads and instagram. (www.instagram.com/calicos.and.curios/) I've tried to do some SEO on my own, but I am certainly no expert.
