You're fucked. Cool settings need stuff going on in them to be worth bothering with. This is why people tend to scrape stories they like for setting details rather than fawn over settings with characters and plots they don't care about. Lacking words to describe your amazing setting is also a death knell, but it's not the most serious issue.

Surprisingly common.
The trick here is that ideas by themselves aren't very useful; they need copious effort to forge into coherent art. This means you need discipline and resolve to do tedious work on a single idea reliably over long periods of time. You have too much creativity as is, and it's already shown you that endlessly daydreaming isn't very productive. Building good habits and working hard are unglamorous and don't feel good in the moment, but what's easy and fun is often not what's prudent.
Start by picking a project. A small one, something that's manageable but cool. It can be anything- writing a novel, programming a video game, drawing a comic. You can even pick something unrelated to art, since the point is to build skills.
Then start blocking out time to work on that project. Doesn't have to start out as a lot, 20 minutes a day might be plenty, if 5 is all you can manage then do 5. You're building a habit, so regularity is more important than raw man-hours or productivity within that time. The trick is that you absolutely cannot do anything else. If you let yourself get nervous and get some quick internet to settle your nerves, you'll just act like you currently do.
If you can convince yourself to stick with this, you'll slowly build skills, both directly artistic and more general life ability.
