Blackmailed into paying money for nudes pics

*i did not pay them *

Long story short, im sure youve all heard this before, i sent nudes to who i thought was a girl, they pulled those and found face pics off my socials, and threatened to send them to my family and friends if i didnt pay. They sent a picture of some contacts, and then made a groupchat with some family members of mine telling them to “be prepared” after telling my mom to block the number and leave the chat, which she did, i also left the chat. I told them police will be notified and then blocked them too. Im kinda stressing out right now bc idk if they sent my nudes to my other family members now. Its been about 2 hours, i haven’t received any texts from other family asking me questions or anything, but im worried they still might have sent something to someone, also dont know how they got my relatives numbers, kinda freaked me out. Is there any advice or anything i can really do now? Or do i just wait it out until theres an awkward convo at the next family gathering?
