How to recover hacked Gmail account?

Hi,

Recovery email and phone changed. The hacker turned out to be someone I knew and she also stole my government identity cards like driving license and old passport.

She cloned my iPhone 6! Such a helpful frenemy she was. She did it by getting my phone serviced. I am on disability and she is a con artist for sure.

I desperately need some help. I don't have a cell phone currently but have a landline. I will watch to see if someone responds. So far, Google has tried to get me at my recovery email but she has access to that account as well.

I wish there was a way to talk to someone in Google's security dept.

Please help!
