Some depression announces itself. Other times it's quieter — a slow erosion of colour from life, a growing flatness, the gradual disappearance of the person you used to be.
High-functioning depression is particularly common in people who are still meeting their obligations — still working, still parenting, still showing up — while quietly barely holding on inside. It often goes unaddressed for years because the sufferer doesn't feel 'bad enough' to seek help.
Depression responds well to somatic therapy, which works with the body's withdrawal and shutdown patterns, and to EMDR, which can reach the experiences and beliefs underlying the depression.
