When Lori Tipton saw an advert on social media seeking subjects for a study on post-traumatic stress disorder (PTSD), her curiosity was piqued. She had already tried antidepressants and anti-anxiety medications. She had been to therapists, social workers, psychiatrists and psychologists. When all that failed to quell her anxiety, panic attacks, insomnia and suicidal thoughts, she sought help from other sources: a dietitian, an endocrinologist, a shamanistic healer and an ayurvedic doctor. She even pursued a yoga teaching certification to become more present and mindful. Nothing had helped.
