Once you had put the pieces back together, even though you may look intact, you were never quite the same as you'd been before the fall.

This quote means that when someone has gone through a difficult time and come out the other side, although they may appear to have recovered, they will not be the same person they were before. This could be referring to a physical or emotional event, or even a combination of the two. When a person has been through a challenging situation, it can leave an impression on them and can cause them to change in subtle but significant ways. In other words, although a person may have put together the broken pieces and may appear to have recovered from the event, internally they may not be the same person they were before.
