I was afk farming in a village and when I came home after a wifi/power outage I found my player had died (which shouldn’t have been possible as I was very secure).

When I hit respawn my player appeared nearby the origin point of the world rather than my bed, and all my work on the world had been reset to how it first appeared except for a few chunks of my sky bridges. When I returned to the village my farms were gone, the village was reset to how it first looked, and there was a small pile of my belongings where I had been afk when I died.

The world used to take up something like 65-70MB and when I logged out it only took up 27.6 MB. How can I get my world back?
