I am so sorry this happened to you, Bizi. I also fell for a scam to the tune of $300 in gift cards. The scammers posed as a friend who asked for help via email. They said it was for their niece's birthday, who was dying of liver cancer. I was eager to help and hypomanic and rushed into action.
I felt pretty silly when i found out it was a scam too. Don't be too hard on yourself, it's natural to want to help, and shows we have good hearts. Let's be mad at the fraudsters, who are heartless. It only takes one time, now i am much more careful about fraud and you will be too.
