Thanks for reaching out. We understand your situation.
Which version of the application are you using? Do you see the images in the delete folder?
You can check this: https://helpx.adobe.com/lightroom-cc/using/restore-deleted-photos.html.
You can try connecting your phone to the computer and navigating to the Lightroom folder on the internal storage to check if you can locate any images. You can also check com. adobe.lrmobile folder in the internal storage of the phone > Android > data > com. adobe.lrmobile > files and check if you can locate the images there.
We're here to help. Just need some more info.
