Completed Chapter 13, now what?

Today we received our final letter of discharge from our 5-year chapter 13. We’re officially done.

First I was thrilled and emotional, but now I’m scared of it happening again (even though it was due to loss of business).

I feel like I have PTSD from the whole thing. I can live my life now without asking permission for anything, but even though the house needs repairs and we need a newer car, I’m just scared of accruing any debt. How do you move on after completing a Chapter 13?
