I don't know why, but I can't imagine my life without Google, I always use their mail, online documents, browser. Gmail is generally a part of me, I can't imagine my work if I ever lose access to my account or block it. To be on the safe side, I always add a backup email address, a valid phone number. I truly believe it will help me if something goes wrong.
Maybe it is the fault of op for not keeping proper record of his log in details. Usually the internet is not a place you don't put your records down accurately. Maybe this is the challenge that he didn't understand. backing your details up or having to save it is important. The solution is to try and change his passwords to the email through other means or device. I also understand that gmail is not easy to operate because it is tied to google and you have many paascodes to provide when their is issue like providing for your mail and google itself.
