They tried to scam me

Amen. My dear friend, before the death of my husband he did a contract with the American government worth $450,000 Dollars, but death took him away before the money was sent to our bank account, my husband was a philanthropist before his death, he also encouraged me to help poor people, because since we got married we have not been able to have any child because of the condition of my health so I have sent some money to my hometown (Ecuador) for the orphanages and have deposited $80,000 Dollars to the hospital for my medication and other needs. My husband encouraged me to help poor people in different countries irrespective of Tribe, Religion and Language, because since we got married we have not been able to have any child because of the condition of my health. I want to donate some money to the less privileged people, orphanage children, beggars and poor widows over there in your country for charity through you. Can you help me do it?
