Some clarity appears only after fatigue leaves the conversation.

Some things cannot be understood while tired. The shape of a problem, what you actually want, whether a relationship is worth continuing, all of it stays out of focus until fatigue is no longer part of the picture. The clarity was not hiding; it was unavailable.

Before concluding anything important about your life, get a few good nights first. If the conclusion is real it will still be there. If it was fatigue, you have saved yourself a great deal.
