[VernCotton]

It's really strange that iOS update is supposed to fix some bugs but it results in data loss. I've been in the same trouble and below it's my suggestions.
Do you have backups available on iTunes or iCloud? You actually can restore your lost data from iTunes/iCloud backups with easy steps according to Apple Support - Restpre from a Backup.

Method 1. Restore from iTunes Backup.
Launch iTunes and connect iPhone to it, then go to "File" > "Devices" > "Restore from backup".
Method 2. Restore from iCloud Backup.
Reset your iPhone via "Settings" > "Reset" > "Erase all contents and settings". It will prompt you whether to restore data from iCloud.
Please note that if you're trying to restore data from iTunes or iCloud backups, current contents on your iPhone will be overwritten.
Method 3. Restore right from iOS device.
It's recommended to try on iPhone Data Recovery, for this software can not only restore previous iTunes/iCloud backup without overwritting the existing data, but also recover data right from iOS device itself.

That's how I restore lost data from my iPhone 6s after iOS update. You can check it out on iFoneTips.
