This post features a sampling of treatments for PTSD.  The film at this link shows several forms of healing through art: making music, painting, and sculpting.  Healing through nature is also shown:  enjoying beauty in the outdoors, and calming one’s spirit by caring for animals.  The film was made in England, but a Google search on “veterans” and “PTSD” reveals that all of these treatments and more are being used in the United States too.
