I have ptsd and anxiety .I have been avoiding people and crowded areas for ten years.now,knowing that this is no way to live life,I've chosen to go to school.I am socially responsible,but still sit in the back of every class.is this a sign of a conditioned response,or would it be more relevant to take the humanistic approach and say this is how I choose to better myself,but I am still weary of my environment?
