well id never heard of this, and im not a fan of the guy, but from my quick perusal online just now of the noise of this drama, id say no, shes not credible.
This was my reaction as well. If a competent doctor had prescribed her medication and she took herself off of it without medical supervision, I think it is pretty reasonable to condition money on going back on medication (or at least going back to medical supervision). Many people who have family members struggling with mental health concerns take this approach.
