Welcome to HCM
We understand your concerns
I went through your problem description. Your sister was deeply in thought and depression
for the past years. I think you neglected it and I am very sorry to say that she had developed schizophrenia
or bipolar disorder
Correct diagnosis and medications can be had fromm a psychiatrist
. You should not waste time because if treated in the beginning, schiophrenia can be cured. Please visit a psychiatrist as soon as possible.
Hope this answers your query. Available for further clarifications.
