If the address is not the same is clear that you created a new account, and memorized bad the password for the account where you deposited burst.... this is not a good think, because your passphrase is you private key to enter the wallet, no possibility to recover, if you can't find the right one, your coins, sorry, but are lost.
If you have the prahse of the account you have the burst in, if you enter in a wallet, your coins have to be shown, if it give you another burst address entering the words, it means that you noted down something wrong, and without the exact password, you can't enter on the account.
