This kinda happened to me. I was going through my minecraft severs, then I found my first world. It was a creative world, I didn't like dying in the game back then. But now, survival is one of my favorite gamemodes.
Going through your first ever made world is like time traveling back in time. It honestly feels peaceful, no problems attacking you or anxiety stressing you, just pure peace
I-... One time I found my first survival world, I didn't even know what creative was. My brother made a house on a island for me.. It was s beautiful.. We somerimes played together in his own world.. The memories start flowing to me now :(
