How you feel about coming home also depends on how you left your mission. If the population you were caring for are safe, if your work will continue, if you made a difference and if you can rest assured that the people you have grown to care for will continue to receive the assistance they need, it balances out. If you left in unsettled circumstances, unsure of the security of the population, tasks unfinished and without a replacement to see them through, it’s tough. It leaves you to wonder ‘what was the point?’ and ‘why did I bother?’. Have we done more damage by giving hope and then taking it away, than by not offering hope in the first place?
