My youtube/google account was hacked!

Hello,

Please help me. My youtube account with over 10k subscribers was hacked just 30 minutes ago.

Full story: I received a youtube collaboration offer mail from someone who acted as if he's from GT Racing company. He sent a link pretending to be Traackr influencer marketing website. I thought it was legit and registered using my Google account. But only then realised it's a fake Traackr website pretending to be the original.

Quickly I changed the password but then the hacker changed it again, removed all my recovery options like my phone number, gmail, etc.

Now I can't log in back to that account to recover it.

Please anyone help me get back my account as soon as possible.

I'm literally crying here because I fear all my hard work in YouTube will be gone if the hacker does something.
