I can find emails on search but cannot open them.
When I search for a term in my emails, I get many results, I can see who those emails are from/to, what date the email correspondence happened, I can see if there were attachments and I can see a snippet of text from the email. But when I click to open the email, I get a blank result like it doesn't exist. Help!

Sounds like your search index has mail in it that no longer exists.
On the toolbar 
> Help > Troubleshooting Information
Click the show profile button in Troubleshooting Information Close Thunderbird In the file window that opened, delete the file global- messages-db.sqlite Restart Thunderbird.
The search will be rubbish until the file fully regenerates, which could take a whole day if you have 10 or 20Gb of mail. You can monitor the status of that using the Activity Manager.
