Did you at least backup your wallet recovery phrase?
I know that when you try to logout they recommend you to do that to avoid any issues like forgeting your password.
Btw, why use Blockchain wallet? Download an offline wallet and you will never have this kind of problem again.
For real my little friend, I try with a random password and they don't send.
If you have created your account yesterday then you should have created a HD wallet meaning you got a recovery phrase when you first signed up for this account in blockchain.info. If you have saved it you can restore your wallet to a different wallet compatible with that HD passphrase. I am not tech savvy so someone else may help you better in this last step.
