My sympathies, thoughts and prayers are with you and all your countrymen. Having lived in New York during 9/11 I can relate to the feeling of loss and dismay that must be felt by everyone of you. However, my advise is you can't let hate and fear take over, then evil has won. It sounds like your compatriots are well on the way to healing, but it will take a long time.
God be with you all.
