I have witnessed a car accident 2 days ago. aside from car accidents from the news, It was also my first time seeing a real accident in my whole life. It was really traumatic for me, I can't even sleep enough resulting in sleep deprivation. Lately, I found myself that I'm having a PSTD and I consult the psychiatrist but still my head is full of thoughts. In your opinion, How will you manage yourself from having long-term anxiety? Are there any natural remedies for this to make it calm down?
