Welcome to Android Central! Sorry, we probably can't help you. Your phone's password and your Google account are pretty important things to remember. If you're prone to forgetting such crucial information, I suggest in the future that you write this information down on a piece of paper and keep it secure somewhere at home, like in a safe.
