Sometimes your strongest proof is simply that the thing meant to end you became part of your story instead.

There is a quiet kind of proof in the fact that the worst thing became a chapter rather than the conclusion. You did not defeat it dramatically. You continued, and continuing turned out to be enough for it to become something you can refer to rather than something you are inside. That is a real accomplishment even though it rarely feels like one.

If you are looking for evidence that you can handle what is coming, look at what is already behind you. Not the way you handled it, which may have been messy, but the plain fact that it is behind you. That is the evidence.
