Being a clinical psychologist is a very emotionally demanding job. It’s critically important to be emotionally prepared for providing psychotherapy.
I routinely monitor my own mood and well-being, since you need to care for yourself before you can assist someone else. Like the airline attendant says when providing information about utilization of a mask during an emergency, secure your own mask before assisting others.
I’ve been in counseling at several different points in my life. I think that the most effective therapists are fully aware of when they personally could benefit from psychotherapy.
