Hi Rebecca,
thank you for sharing!
So what we know is she had a fainting incident 4-5 months after giving birth. She went to the doctor who found her thyroid hormones irregular and on the low side.
So the fainting is an immobilizing "minus"-reaction, very short-termed. There are 2 certain points in our phases model which could relate to this - the UDIN (initial stress reaction) or the healing peak..
How would we find out which one this was for her? Any Ideas?

Then I'd like to know what the specific symptoms are that she felt more of, and that started in 2013? So I'd ecpect something significant.to have happened at that time, that primed her.

Then we have another thing that was triggered by the diagnosis, so it is not equal to the reason for the diagnosis: That's her feeling of shame, blaming herself for "family patterns". This is a self-devaluation.

She is in a state of "waiting for something to happen" and that's enabling her to tolerate life at the moment. It seems to me that she has basically an active and energetic personality which was set on pause during her pregnancy, now she likes it to return to "normal" but has fears around this diagnosis.

With these informations, where do we see she is in the process and what might keep her from returning to "normal" and to health? 
These are the things to raise awareness about and to help her with if needed and wanted.
