The first time you start over, it feels like losing. After that, it feels like a skill.

Your first rebuild is terrifying because you have no evidence you can survive it. Once you have done it and come out the other side, the same situation reads differently: unpleasant, but known. The fear was never about the difficulty so much as the unfamiliarity. Each restart adds proof to a file you can consult next time.

If you are in the first one, write down what you are doing and how it went, for later. Keep the record even if the ending is not good yet. When it happens again, read your own account before you decide how bad this is.
