what should i do if m being blackmialed online with a video?

[confused]

Im only 14, and i was bored so i went on a site where i started talking to someone and we went on cam to prove to each other we were real, then he said that the video got recorded, and because i was apparently rude to him, he threatened to edit them and post them on facebook unless i did what he asked, so he told me to go on another website where he promised not to record me, and he made me strip and masturbate and stuff. i was so scared and i did what he asked, then he said because i played him for a fool, he played me for one and he did record it. he won't delete them and said he would post them on facebook. im scared and don't know what to do, he doesn't want money, he just said he wants me to go on cam and do more stuff but i don't trust him not to record me, what should i do, i don't know if he put them on facebook or not coz i don't have facebook, and he uses fake names on skype and stuff. i don't want my parents or anyone to find out, what should i do. if anyone see's them i may aswell die. plus im only 14, and im scared i'll go to jail for doing it in the first place, i know i messed up but i can't take it back and i don't want to do it again but unless i do, he said he won't take the videos off facebook. what should i do?
i can't tell anyone, if i do then i'll never be able to show my face again, in school something that wasn't as bad as this happened, and she committed suicide, i know i shouldn't be scared, but i am
the person doing this is only about 16 too
