Is there a jurisprudential rule that can be relied upon to address financial matters related to medical conditions shrouded in doubts or deceptions, especially in light of suffering from excessive obsessive thoughts that disrupt interests?

A doctor is not liable if he performs his work diligently, strives to diagnose the case, and takes appropriate action, but it turns out to be ineffective. Rather, he is liable only in cases of negligence or dereliction of duty. There is no harm in complaining about the doctor to the competent authorities to ascertain whether he was negligent or not. It is advised to disregard obsessive thoughts.
