It sounds like you have accidentally turned on the line numbering feature in Microsoft Word. Here's how you can turn it off:

1. Click on the "Page Layout" tab in the ribbon at the top of the screen.
2. Look for the "Page Setup" section and click on the small arrow in the bottom right corner of that section.
3. In the "Page Setup" dialog box, click on the "Layout" tab.
4. Look for the "Line Numbers" section and click on the drop-down menu next to "Count by."
5. Select "None" from the drop-down menu.
6. Click "OK" to close the dialog box.

This should remove the vertical numbers from your document. If you still see them, try clicking on the "View" tab in the ribbon and making sure that "Print Layout" is selected. If you have any further questions, feel free to ask!
