Cant log onto 2nd account

The problem i have is that i cant log in onto my second accout.
I tried to changed the password (via smartphone with some internet issues) but i probably misstyped the password with the same mistake twice.

So:
I can name my old password
I can name my new password (like how it should be, probably with one letter being different)
Due to the fact that i cant remember the right gmail account I cant reset my password via homepage... but the email should be pretty similar to my real life name.. so i can tell you my RL name and it could be doublechecked

I could even name ever char on ever server on this account + having screens etc...

And help from anyone, what can i do now? How do i get my account back?
Can i somehow see my gmail address without logging in? So i can reset my password and log onto the gmail accout... because i will probably remember the password for this gmail account.

Need help !!
