Lush caves, don’t stand on those leaves taht spawn on the ground, those are drip leaves, they drip when you stand

What are the realistic things you’re talking about?

The first mistake was not creating a backup for the world, now ever since I lost full netherite on my world about 4 months ago I’ve stopped playing survival, what you can do to get motivation is try playing modded survival, gives you a ton of new goals and achievements to explore, if you don’t want to restart in survival I suggest you start some building projects on creative, I’m currently making a big village on a massive island. Build projects give you dedication to finish the build and you’ll feel pleased to see such a big project built all by yourself, you get to see the progress and it feels refreshing and achieving to finish projects, after that hopefully you will improve your building skills and regain your motivation
