It is interesting that some posters believe the Industry would "expel" anyone suffering from stress due to life pressures. However, surely if a person cannot cope with a divorce, financial pressures etc they probably can't cope with the stress they might encounter on a flight deck.
I am not unsympathetic to mental illness but I certainly would not like to board an aircraft if I knew one the pilots had recently suffered a mental breakdown.
In my view suffering from such a condition should be a licence terminating event. Period. It's harsh but I see no alternative.
