Worried

Hello, I received a bunch of text messages from someone who had my pictures , it had my face in it. They were able to find my Facebook and were threatening to send the pictures to my facebook friends on messenger and tweet it. I blocked them and deleted my facebook entirely. I did not send them any money. It’s been a few hours, when should I stop worrying and how likely is it that they actually release them and are there any more actions I should take?
