Even people with MbP can back off of their crazed desire for more medical attention if they're receiving it from another quarter. Susan was still hitting up the UCLA ER every few weeks until spring 2017. They got wise and she was forced to back off. Then, by June, she found Kaiser and Rizvi, and got her dream med for Bodhi plus a hike in all of Jani's dosages. She also started pumping out videos on the channel rapidly around the same time.
So Susan replaced her hospital attention with the attention she got on YouTube. She never stopped her MbP behavior, she just temporarily changed the attention source while she was getting all the drugs she wanted for Bodhi (when she was denied lithium she was already starting to lose it though). Now that she doesn't have her pills, she's back at the ER causing a scene every other night.
