"If i move a file from the drive to my PC (macbook) will that file still be on the HD? Cuz I just deleted those files from my computer :( Im freakin out and my HD is at home 250 miles away"
Assuming you are dealing with the GUI (Finder), here are some terms that will help you:
"move" does not ever happen between two drives in the Finder, unless you installed some special move software. You can only copy in macOS. Then the original file is unchanged, still there. TO CONFIRM THE FILE IS STILL THERE, SEARCH FOR IT. If you hate the original file, you must drag it to the trash, and then empty the trash.
"drive" is a general term that can be applied to the internal startup disk or to an external drive. We have no idea which one you mean.
If you copied files to an external drive, trashed the originals, emptied the trash, and now regret it, JUST COPY THEM BACK.
