DG, I would venture to say that the sitches we find ourselves in are new to most of us. Expect yourself to flounder at times as it is part of the process, and we are not perfect. Be kind to yourself. It's not easy and it takes a long time. Learn from your mistakes and keep moving forward.
One thing I have found that helps is to tackle one thing at a time when you're trying to reorganize and follow through to completion. Break it down if you need to, to avoid being overwhelmed.
