Greetings,

Sorry to hear about the situation.

Easiest solution: If a guest changed the password, contact that guest and ask them for it.

Failing that: Change or reset a user account password on your Mac - Apple Support
If none of the options in that article apply to you, then you have two remaining options:
Contact Apple for help reseting the password.
Erase the computer which will remove all your data and also the password: OS X: How to erase and install - Apple Support

Hope that helps,
Madison

And No I don't have important files on here either so I don't think I need to back up my stuff.
