It was not meant to be a wise a** comment in any way.
Just a friendly reminder to the OP going forward that a situation like this can easily be avoided if they leverage the backup tools that are available to them. Too many users find they have lost some or all data after making a simple mistake, or through no fault of their own other than not giving backups a level of priority.
On a modern Mac that uses flash storage, once a file is deleted from the trash it is pretty much guaranteed to be obliterated immediately. The only way to recover a file will be from a backup drive.
An inexpensive example of an external drive that can be used with the already installed Time Machine app would be a laptop class 2.5", bus powered HDD such as this $88 2TB drive from macsales.com. It's certainly not the highest quality b/u drive available, but something is (usually) better than nothing.
fyi, any underlined blue text found here in the Community is usually a clickable link to additional info and/or guidance.
And... command-shift-delete is the keyboard shortcut to immediately empty the trash, so don't press it unless that's what you intend to do.
