Nether Teleport Issue

Just spent hours and hours enchanting gear to go into nether and use beds to mine Ancient Debris. When I went to teleport, the game froze on the loading screen. So after about 10 minutes I closed the game and reopened it. When the game loaded I was in the middle of God knows where in the nether. Needless to say I eventually ran out of a stack of food lost all my enchanted gear and house of play time. I'm done playing Minecraft because of the countless hours I lost due to the game not loading properly. Is their any way to revert back to a save before It glitched out and caused me to randomly spawn somewhere in the nether causing me to lose everything.
