I assume There would be a lot of resistance to therapy and/or psych medications. I agree with looking into the faith organizations for now. There are spiritual groups that help with these sorts of Issues and may be more acceptable. However, if it is actually depression then she will need treatment, and that may involve an intervention from someone who lives nearby. I’m not sure if she lives in the US or overseas. There is a shortage of trained professionals in this country and it was really hard to find someone who could even see my mom, never mind dealing with the stigma and resistance, But it’s well worth the effort.
