See, I've never had 550 likes on anything I don't think. That feels like a lot to me. The thing is I genuinely don't know if I've had more or not, I'm not even entirely aware of my numbers on tapas, and that kinda rules. It took me a lot of time and training to get there though, and it is really hard at first.
What really helped me was tabling at conventions and doing things in person. For one, having someone, anyone, like your stuff enough to buy it is pretty overwhelming at first, and is something that online is way harder to do. Second is that seeing people in person reacting to your art is way, way healthier than online, especially if you can laugh off any off-colour comments. People in person aren't quantifiable the way likes and even comments are, you lose track after 5 if you're not counting (and you shouldn't), but you remember the faces, you remember what they say and how they say it, you remember what they looked at and what they were drawn to. The kindness feels more human and connected, not just a competition with yourself to make the number go up.
Numbers only start mattering when they allow you to do more stuff. Crowdfunding a print run for example is one of the times numbers truly made me feel appreciated as an artist, but it was because of the connections i'd made with fellow artists and friends over the years that it was a success, not the online numbers on their own.
Being able to say "i did this and saw it through even when it was hard, and I made a ton of friends along the way" is a really really great feeling, I really want you to concentrate on that and get there.
