How to get my gmail password back?I lost my gmail password get it back I need my secu

Here are the instructions from Gmail:
I forgot my password - Gmail Help (http://mail.google.com/support/bin/answer.py?answer=12381)

I had setup the 2-step verification on my on my uninor number but it expired for some reason and there is no way to get it back...

Now I remember my password but not able to access gmail.

When I filled up recovery form, Google is asking some question like when you have created this account and the same like this which I don't remember and I need my gmail at any cost because it was my permanent address...

Is there any other way to get my account back?

Please help me...
