The truth of the matter is, you can't get your password back or make withdrawals from that wallet anymore. That's why they always warn to write down your secondary password and even take a step further to verify if you did by asking you to write it down. It's a step to ensure tight security and avoid the case of missing funds and we accusing them of tempering with our wallets.
Let's just hope what you've got in that wallet isn't huge because, it is as well lost.
