I really like thinking in abstract and recently had the chance to visit a place again after a long time which is just not the same anymore. The environment and people had kinda become like 'this' from the Powerpuff Girls episode.
People had deteriorated mainly because of age.
So I just need a word for this whole situation. The closest word I can think about is apocalyptic. But I think, of course, it's a bit extreme. Since there hasn't been any major event. It's just that everything has lost its energy naturally due to not good planning, for the worst. Please suggest.
