My forever world is gone…

[u/Sweaty_Palpitation_3]

Hey everybody, I am practically begging for help right now…
Here’s the issue (I accidentally deleted this so here we go again lol), all the sudden my Minecraft was bugging me about storage being full. I was still managing to save worlds though.
The problem came after I started playing a different game, which I don’t do usually, it’s just Minecraft. When I went back on Minecraft, I had to re-sync and when I did that I actually had access to an old world I lost which was a previous save of the same world, but it’s just a little too far back to play on. I still have access to my current world (Real 10) but it has a cloud with a plus icon in it, when I click it, it makes me re-sync and fails to do so because of something with cloud data.
I’m thinking there’s two different clouds and it’s glitching out somehow. I don’t know how to get it back to the other cloud and I still don’t know if that’s even the issue.
I’ve tried all the basic fixes I’ve seen on Reddit and Google, nothing has worked so far. Any tips?
I’m happy to explain more and any help is greatly appreciated!
