Welcome to the forum
It sounds like you have been very understanding and patient with your friend. The way she replies and responds can be due to the disorder as ones mood can be up or down.
Is she attending therapy as well, or just using meds? Therapy can be helping for her, especially now that she may be experiencing different mood swings.
I would suggest you let her know how you feel, and that you care and want to help her. However, she must be
open and willing to accept your help.
I hope things get better. Keep us updated on how you are doing.
