I REALLY NEED HELP!!

I am speechless.. I just found out that someone created a fake profile of me with all my pictures that I posted on instagram on a Gay Social Media platform... WHAT DA FUCK?? I really have no idea what to do now.. Please help me I want to get this sue this asshole asap but how do I find out who this is??

UPDATE: Thank you guys for your support! I asked the friend of mine who showed me this profile if he could make another account because the faker blocked him on his actual account so he did. I told the faker that I have no idea what I did to him that he actually does shit like this and if he doesnt delete everything within 48h I'll inform the police about it.. And luckily he believed it and deleted the profile instantly.. 👌🏻
