Usually something like, “This too shall pass” or “The only constant is change.” Reminding myself of the impermanence of every situation makes present difficulties bearable.
What also helps me is the prospect of emerging on the other side of the situation as someone with more experience, more self-understanding, and greater resilience. Those traits are high on my list of personal values.
Nah, I won't return in a meaningful way. Come June 30, I'm fully deleting my 10+ y.o. account. I may make another burner one to be able to follow a few niche communities (mostly snark subreddits) that I'm certain won't be moving over. But I don't plan to contribute or even lurk in a meaningful way anymore.
I'm excited about the promise the Fediverse holds. It's refreshing to me. I've been longing for a better social web experience, something like I remember having 10-15 years ago, and I'm feeling hopeful that the communities developing here can give me some of that magical feeling back.
