How should I handle this (UPDATE ALREADY!)

Darrian

I got a message from my best friend asking if I had given her number to someone who has been stalking us for nearly 2 years. The girl stalking us used to be my friend until she started getting really creepy about my relationships. She doesn’t even know my best friend and she’s claiming to be her friend. If making multiple Instagram accounts, scouring up her brand new email and phone number doesn’t scream stalker than you should see the screenshots my friend sent me just an hour ago. (Last names blurred for security)

Email-

This is the final straw for the both of us. She pretended to be me to get my friend’s attention! I’m going to the sheriff’s office tomorrow and finding out what I can do about this. My friend is going to go get a restraining order and hopefully she will stop. I’m considering messaging her myself about it but I don’t want to stir the pot. What should I do?

Update:

So her mom (actually her grandma) messaged me on my art account and my personal account. I’ve given her warnings and if she tries to contact me again I’m going to be in contact with law enforcement

I’m done with blurring names
