That's not good. I can't confirm it will help but a psychologist deals with mental health and mental processes
I am so sorry to hear about your friend. I do think that is a good decision seeing that mental health is a psychologists area of expertise.
I have a friend that seems to be having some emotional issues with finding out that her brother has cancer. I wonder if seeing a psychologist would help?
A psychologist is a mental health professional who evaluates and studies behavior and mental processes.
