Welcome to the community, CC49!
I'm sorry to hear about your WD My Passport issues.
I'd suggest you to try using a different USB cable and try a different USB port on your computer. If that doesn't help, I'd suggest to plug the drive in another PC altogether and check if it get recognized there. Is there any indication of the drive spinning/powering up?
I'd recommend you to check Disk Management afterwards, and see if the external shows up there. If you manage to do so, you can try testing it using WD's Data LifeGuard Diagnostics. Running the QUICK and EXTENDED tests will help us determine the health and SMART status of the WD My Passport. Here's a link to the software:
