My client spoke of sadness and how she is scared to express sadness because it will bring negativity into her life. Is sadness a negative emotion? I will argue that it’s not. Sadness is a natural part of our lives.
By expressing the sadness you let it go and allow space for the happiness to unfold.

Psychotherapy  provides a space for you to explore the uncertainties that life can bring
It helps you to ask yourself what lies behind the emotion and what it means? Life is full of moments of sadness, anger, guilt or shame and also about the moments of happiness and successes.

This poem of Rumi is very befitting of what I am trying to saying above,

'This being human is a guest house. Every morning a new arrival.

A joy, a depression, a meanness, some momentary awareness comes an an unexpected visitor. Welcome and entertain them all!

Even if they are a crowd of sorrows, who violently sweep your house empty of its furniture, still treat the guest honourably. He may be clearing you out for some new delight. The dark thought, the shame, the malice, meet them at the door laughing and invite them in.'
