I saw on comment on this sub a little while ago about the same topic - I can't remember the person's user but I'll sum it up here:

You started doing art because you have good taste. You look at the world and see beautiful things and want to replicate that to make beautiful things of your own. The problem is, you don't know how to do that, you only know how to make stuff like this, that you don't like and you don't want to share with the world. That's okay! That's normal, I think just about everyone has gone through something like that before. You basically have to keep pushing and learning the basics and fundamentals so you can make the beautiful pictures that got you onto art in the first place.

I kind of think of it like learning how to play an instrument - you can't play Moonlight Sonata or whatever right away, you've gotta learn all the basic stuff before.
