Someone stole all my money

A fraudulent caller convinced me out of $8,500 that is all the money I have! I know this sounds crazy but I am being for real I don’t know what else to do so I am trying to just make it through the rest of this horrible year! Let me go ahead and just explain what happened, again I'm super embarrassed, a man called me saying my identity had been stolen and was being used illegally in TX so I of course questioned him and he then called me back from the FBI phone number in TX which I verified online to be the real number. They had me take the money out of my accounts and put it all into one of my accounts that they already had hacked into. I am a single mom with two beautiful girls and this is really all I have! Any help will be greatly appreciated. Sending love to anyone able to help me! And to those willing to share this. Thanks so much!
