In terms of a call center, the company I work for is health care. They have a mental health advice line - it's below the level of crisis line and is not with primary MH person. They will listen, be supportive, help navigate the various MH services available, and such. I do not know the level of training/education they have. The one I talked to seemed to have a decent level of training in terms of addressing my stresses, listening, having me felt heard, and understanding why I was looking for what I was looking for based on my therapeutic needs. I wouldn't have been surprised to find out that they were a therapist or had some level of counseling education.

DP - sorry you are going through this, it is a nightmare.
