It is never easy if we become face to face with these kinds of traumatic asphyxiations of our human body. I've experienced reactions similar to what she went through from overworking/overheating of the body should it requires rest. Takes you by surprise and we should not be afraid to say 'no' to decisions we might not be ready to meet at full length. I have found the reaction to be of the most deathly and scariest nature so we need to be prepare and to take things lightly but fairly according to our self-cultures and knowledges.
