Between her meds giving her negative side effects, she could be feeling left excessively fragile after realizing what she had been struggling with for a long time was REAL. I know my Mother didn't take it well when she finally got help for what she was going through. It took a therapist wanting to talk to her 3 or 4x a week to get her through her anxiety about it. But honestly... She'll be okay. I think she just has some unresolved issues, both related to bipolar & herself as an individual.
