Yes, I feel like a failure at times because I can't hack what normal people can. I have not achieved what I expected to, hoped to, could reasonably have done.

However, all I can do is my best from where I stand. We have no guarantees where it leads. I believe we have to accept that. It's reality. IT doesn't mean there is something wrong with you. Judgment of "failure" is not objective or rational. It's a judgment, and it's damaging. The disappointment hurts, but it's not necessary to turn it into a self-judgment.
