Hey jojo-camaro,
Thanks for the question. Unfortunately, if your iPhone is in recovery mode the only solution is to restore it. However, if you made a backup previously (or if you had iCloud automatically back up most of your information) you can restore the backup after restoring your iPhone:
Restore your iPhone using iCloud - iCloud - iPhone Basics - Apple Support

You can also salvage data from any iTunes backups that may have previously been made. To check if you have a backup in iTunes, see the following:
iTunes: About iOS backups

I understand how frustrating this may be, data loss is never fun. But I am here to help you salvage as much data as possible. If you have any further questions please feel free to ask.
