There's also other angle to look at this things: the haters are the sign you are successful.
I've joined hive/steem because I was told the community here decides what something is worth. I would hurt (emotionally) if someone would downvote all my posts all of the sudden, but this is the way things work and I think it's beautiful.
All in all, you're still growing despite the downvotes and you should think about that.
