Shame at what's weighing you down breeds an almost frenzied desire to isolate. Mustn’t be discovered by everyone else, by anyone else–no one will understand what you’re going through; shame convinces you that you are the only person who has “failed” in this way, fallen down or been dragged down by someone else. Isolation, in turn, feeds fully off the stories you continue telling yourself as the shame piles higher and higher, burying you under its massive, crushing layers.
