Facebook help please?

ok, so a couple months ago i was on facebook and all of a sudden people were getting added to my account that i didnt even know and people were getting deleted. then my friends started telling me they were talking to me on chat, and i never was. so i trying disabling that account and it said it would be disabled but it never got disabled. well i made a new one and then someone said someone is talking to them on my old facebook again and this was yesterday. so i went to my old profile and repoted them for impersonating me. then today i got home from the moves and MY new profile was disabled. so i went to go on my hacked account and my email had been changed to a profile whos name is chelsea south.(my name is chelsea north btw) which is really weird. so they must have changed my old email to theres. so i have no way in loggin in the hacked account. so they keep talking to my friends, not only that but all my friends say they know EVERYTHING ABOUT ME. so they are tricking them into thinking its me talking to them.... so i made a new one and im having all my friends report them for impersonating me. has this happened to anyonelse, and do you have any solutions. its really scary. pleaseeeee help me.
