Oh my accidental re-set...Don't feel bad it has happened before. First I would save all files to your laptop then install gCloud from google store then set up an account where all your files are synced and backed up in the cloud.

Next try to recover from previous restore point on your phone it may work.
Try recycle bin restore..
Then try Dumpster on the Google store

To root or not to root.....this is tricky I wouldn't pay to have it done but find an experienced friend who can help you...your data will be gone so be careful and backup before you root.
Good luck...
