i got groomed and im being blackmailed

What do i do about this, he is 6 years older than me, he followed me on ig and said hes new in my city and asked me to help him find where to buy some vapes that arent sold in stores and that he would pay me if i did, we talked and kinda became friends after, and at first we were just supposed to be friends and he would give me money sometimes and free weed, but it ended up going too far when once i was at his house the weed hit me too hard i literally fainted and fell on him idk after that he started acting different, like he thought i would wanna be together with him, i said id kiss him for 30 e but then i said i actually dont want to and dont need the money, i didnt wanna meet him anymore i told him that and then he started threatening me and shit ofc and i blocked him, but somehow he still had all my followers and was reaching out to everyone and saying he wanted all his money back from me, i was okay with that, he said if i gave him the money back in 30 mins he wont do anything and we agreed on that, then last minute he said i have to also make out with him for 10 mins and then he wouldnt tell anyone, he also tried to convice me i took my clothes off while high which i very well know i didnt do, i said no to the 10 mins thing, and i guess hes gonna ruin my life now, he wants to tell all my family and people that know me and put me in a group home, is there even anything i can do at this point
