Forgot Gmail password

My baby daddy stole my phone and changed my gmail password. When i try resetting it, the reset code goes to my phone i have now , then it ask me for a email to verify and i give it to em and i verify it also. Then it ask me to enter the month and year it was created... And i cant remember cause its been close to 10 years since i made account. Help how can i bypass that. !!#!/%#$ i had have close to 7000 photos on drive.
