I feel very much the same way.

In 2016 I was coming out of a nasty depression. I wound up falling into a smaller subreddit and even became a ‘cool kid’ with a group of folks from it. We spun up a group chat and became very good friends - to the point of sharing our lives, meeting each other, and in my case - I started dating someone from the chat, and she moved halfway across the country to live with me. She is my forever person.

Last week, I was thinking about what had been lost in the 10+ years of comments and posts that I had either overwritten or deleted. So much of my life was shared there. And so much of my future will be determined by experiences there. I legitimately cried.
But change is inevitable, and we’ll always make the best of it.
