Can’t access old email adress

so yeah, this kinda sucks. Today, i discovered that i have an old Google+ account which holds information that i want gone from the web.

after a few minutes of research i came to the conclusion that it was created using my old Hotmail account as a login, and a password that i have forgotten.

So, i tried to use the "i forgot my password" thing on Google+, but it shows out that i need to be able to remember when the account was created and such (exact date) which is almost impossible when it's as old as it is.

So, i tried to access my old email in order to recieve the alternative password Google would send me, but it shows out that i'm unable to access it (the password i made it with simply doesn't work)

I have a slight feeling that i have done a password reset once and recieved one of those random number codes as a password, but that would also be almost impossible to dig out Again.

therefore, i pressed the "forgot my password" thing on my mail login page, and it brought me to a place where i could either have the password send to the alternative email i put when i created the email (that old email adress is doubtly even existing anymore) or answer some questions such as name, date of birth, etc.

I then proceeded to fill out the question thing, and i got answers the answers back telling me that i didn't have enough valid information on the old account to access it.

I have tried almost everything, and i'm getting kind of desperate.

Please help me
