Just got blackmailed

Hi I just got threatened 1000£ to have my face and a nude leak in social media, but the thing is that they don't have my name, phone number email, i didn't engage in anything and reported and blocked them immediately. I practically don't have any presence online and also gave a wrong location. I was blackmailed by a chat screenshot where my face and nude was leaked. I kept checking google images and yandex but there is no trace for an hour or so, I don't have any facebook or snapchat account. I've also deleted my account from the site.

How likely will my face be leaked and will it further escalate, please help me immediately because I'm feeling like ending myself from the guilt
