Im trying to reset my security questions

i called apple support yesterday for the problem of forgetting all of my security questions and they told me to go to iforgot.apple.com and went to forgot security questions, went to reset my security questions after signing into apple id and everything clicked on forgot it questions. Asked me to pick one of the security question and anwser it. i forgot all of them made them awhile ago. what do i do now is there another alternative or how do i go about this. To *** im locked out of my iphone because i forgot my passcode when i was drinking one night and deciding randomly i guess to change it. Now im locked out and it is telling me iphone is locked to user and i have no way of getting in. unless i can change security questions, thanks in advance
