I think I might understand what you mean—especially now when it's important to mend from this last therapy experience and find a purpose in it—but I think it's sort of like saying it's necessary to drink and drive until you get into a wreck so that you learn how to not drink and drive.

We just keep repeating the same crap until we wake up and move on.

Even so, you do have your own unique path and are finding ways to grow, so there's a lot to be said for your ability to heal.
