Where the Heart of Anti-Shurtugal Rises Again.

I think you're putting too much pressure on yourself. You don't have to create something completely original. That's basically impossible anyway as through human history it's a given that any concept has already been thought of by someone else either if it's been written or exists only in someone's head. Every day on r/writing someone complains their idea is already been used, but what they don't understand is that's just a trope. Just an idea. What makes ideas and stories stand out from one another is the combination of them and the details. You can make almost any two stories sound like one another if you summarise them in the simplest way.

So you have things you want to write? Go ahead and do them! :) Use those dime a dozen races with a spin on them that makes them different enough to feel fresh without giving yourself the trouble of trying to create something completely new - that someone else has probably already thought of anyway.
