Anything that takes you up the Tone Scale is valid therapy. Aesthetics and beauty are right at the top of the tone scale so one idea is to pick an art form, writing, painting, singing, dancing, music, drawing, any one, they are all therapeutic, and start to create with it. Learn about it. Study the techniques used by its masters. Get competent with it. Get really good at it. Teach others what you know. Who knows where it might take you. Wherever it takes you, you will be happier traveling there!
