When do you know you have to go see a therapist or psychologist? i have a family dilemma which is grinding me and getting worse and i feel i am slipping into more sadness and it has a bad effect on my marriage and son?

Emotion stress : One can physically work hard, rest then recover. Emotional stress is not that easy. It does not allow us to rest, wakes us up at night, and makes the mind run. Inevitably the mind and body get drained, fatigued, and that makes one's mood worse. Seeking a therapist like a psychologist is helpful to get the mind out of the cycle and to develop a perspective of recovery.

PSYCHOLOGIST: If you feel the need for help please see a Clinical Psychologist with expertise in multiple types of psychotherapy and you may need medication from a Psychiatrist. It's really up to you.
