If someone starts talking too themselves it does not been there is anything wrong. Sometimes when we are expressing our feelings and emotions and there is no one there to listen there is one person who does listen to what we say and that person is god.
When we say how we feel god sends a message to the guardian angels. The angels show us that we are not alone.
If she is feeling upset she could write down how she feels and her problem will be solved.
This is something which doctors donot understand.
