Can't log into my email

Hello, ive been trying to log into my account for the past few days.
The problem is that when i log into my email it says:
It looks like someone else might be using your account
To help you--and only you--get back into ***@***, we need to verify that it's yours.

It asks me how i want to retrieve my security code and the choices i have is:

Email ?fa*****@hotmail.com and i cant verify my account

?fa*****@hotmail.com is my other account that i can't acces into.
And i done that survey thing many times but it is too little info.

Help me i have important things on that email
