Go to the Trash folder. If your emails are there, just select the ones you want reverted, and drag it back to your designated folder, e.g., Inbox. Otherwise, your emails should be in Archives, or something similar.

back up profiles folder first:

/home/<user>/.thunderbird

Try to insert the folder in another thunderbird to see if it's a problem of thunderbird or your profile.
