Sorry to hear you're having trouble.
However, I'm afraid that if you've forgotten the password for your account you would need to go to https://microsoft.com and when get to the login page you can click on Forgot then follow the instructions to change your password. You could also try the Microsoft Account Recovery Form https://support.microsoft.com/en-us/accounts-billing/manage/help-with-the-microsoft-account-recovery-form if it applies to you.
Please note though that if you do require a Two Factor Authentication code to get into the account but you no longer have access to the method of getting the code then there would be nothing more that you would be able to do.
