Forgetting my password and my recovery phrase But I'm still on the same browser

Today I Entered the backup phrase of my MetaMask in Chrome then I realized it was the older account. I Created a new account two days ago and I deposited all of my savings in there. I was in a hurry that day, I copied the backup phrase in a text file, but I forgot to save it. I copied the password from so I don’t remember that neither.
Now I need to log back in. but I don’t have my password nor my backup phrase.
But I have the backup phrase of my two older accounts in this browser. would it help?
I’m still on my browser. is it all gone? did I lost all my savings forever? Is there no hope?

I got the Vault data, but I don’t have the password. what should I do?
