Minecraft deleted wrong world!

So, I was deleting my old redstone test world. I clicked it, I clicked delete, and I clicked yes. Just to see that Minecraft deleted wrong world. It was my YT let's play world, so it was extremely important to me. Unfortunately I did not have back up. I'm 100% sure that I was deleting right world, NOT the let's play world. Is there any way I could get my LP world back?
