Unfortunately, jeffreythefrog is correct about your user files and data being gone.

Without a backup there is no recovering data without spending $$$$... lots of $$$$.


The Time Machine backup solution is built into the macOS, so for the future security of your data, please see:

sorry but, if the data was deleted and you have no backup, that data is gone. that is why backups are so very important. take this as a learning experience.
