To properly envision what is going to happen when things crumble down

Things would be so much easier if it's all just hurt and pain. But it's not like that. Things are all fine until the minute that they're not. The constant identification of guilt (wondering where have the things gone wrong) is what drives me crazy, while tiny bits and pieces of judging, misunderstanding, criticism or correctional advice crushing in like sandstorms.
Sometimes I wonder, at which point will the bits and pieces crack me down, because I fail to withstand the weight of one more grain of sand? Soon, perhaps.
