I got a friend that worked at the funeral home. T thought she was high functioning , but it turns out that doesn't matter the mind/brain is very fragile if too much around those symptoms it can be a very quick fall to something extremely traumatic before recovering the kids traumas and the significant traumas along the way.. As for advice I'd just generally try to keep away from things of the senses until a certain point where you and system is safe to remain high functioning to do a reintro etc to the world.
