It could have been me:

There may also be something different about a supporter-supportee role in disaster recovery that makes the boundary more readily permeable. Rightly or wrongly in your typical health or social service role in non-disaster times, it is easier to feel that the client is in different circumstances to yourself. However, the identification with people you are supporting is stronger after a disaster as there is the sense that 'it could have been me'.

...these are ordinary, everyday people who find themselves in circumstances where it's traumatic. By identifying with people, professional boundaries blur. It is a unique stressor. John Richardson - Australian Red Cross
