Part of it is learning to forgive yourself and another part is framing your situation in the right light. Essentially, you may no longer be up to gold medal standards and that's ok because that's just for now. It's also perfectly ok to be frustrated. But then you have to to think about whether you are doing well for where you are now because that's what matters.

You can also try picturing it as a treasure hunt. You have buried all this hidden treasure (technical knowledge), but the map you left yourself got washed in the laundry so now you have to go around piecing it together, but hey, every once in awhile, there is treasure!
