Welcome to the Android Forums!

Your only option at this point may be to do a factory data reset on the phone. This will clear the pattern lock but, unfortunately, will also clear all of the other data stored on your phone. You could try recovering your Gmail password via the Gmail web interface but others have had issues doing this as the changed password doesn't always sync to the phone in a timely manner.
