Dear... Sorry to hear that, but seems you jumped in this without any basic plan or projecting your steps. At first, you should have some basic knowledge then run the Business or project.
In general, $200 is not a much investment but could be effective if you have the right niche research, product research, some basic SEO, landing page customization/optimization, and the whole web page (if it's a general store). Dropshiping it's not so simple these days, sometimes you could have a bit of luck, but sometimes you could throw a lot of money into testing.
FB Pixel is also a very important part, where you should "feed" with traffic data and reuse that. The basic SEO should be done and optimized before starting any ads or promotions.
I could suggest using IG, Pinterest for some free traffic. But again if someone intent to buy from you it should have a positive impression at first glance. That included the points above (branding, design, website and pages optimization, mobile-friendly,).
In the end, I highly recommend watching some tutorials and free courses (do not go straight for paid ones). Maybe you will need a few some for the Dropshipping process and another one for FB ads or Social Media promotions.
I'm not sure what any of us could help you.
