Question SD card help, Not recognized by phone. PC says it is write-protected

My micro SD card(which worked fine for two years on my LG Optimus S) has stopped being recognized by my Galaxy S3 after about 3 months of use with no problems. It occurred very randomly, I don't believe I was even using the phone when it happened. I just wanted to check my pictures on my SD card one day and they were all gone... I am unable to mount the SD card, as it tells me to insert one.

After hooking up the card to the computer, I tried to click on it and it tells me it's inaccessible because it is write protected! I've ensured that the little lock thing is unlocked and all that. I don't believe I have a recent backup of this card... Am I SOL?

It could very well be worn out. Flash memory devices like SD-cards have a finite number of times they can be written to and then they'll start to fail. Try replacing it. Make sure you try to get a good quality one, like Sandisk or Kingston possibly, but beware there are many fakes.

Welcome Drbob1!
As mikedt said, it could very well be worn out as sd cards have a certain life span.
Also, I have seen alot of threads where the S3 has boogered sd cards

You could try this to recover some files:
Recuva - Undelete, Unerase, File and Disk Recovery - Free Download

Or this to format it:
https://www.sdcard.org/downloads/formatter_3/

Or as mikedt said again, it could be time for a new one.
Very important, hindsight, to backup sd card files on the computer or in the cloud
