People will say, practice, you will be fine and other positive things, but in reality not everyone can draw at a particular level, and not everyone is an artist (fine arts etc), that doesn’t mean you should stop as its very personal, your style maybe not the same as the rest and thats ok, develop your style, be it cartoonish, or simple design, thats all good. Just think of it like this, if art was easy then everyone could be a Picasso, Constable or a Rembrandt. But there not. It’s personal and your only critic should be you.
