Okay, I was able to rez. I'll go through my troubleshooting steps, however anyone in the tech industry is going to cringe at my last few steps because I tried 5-6 things at a time and that was the one that worked. Sorry that I couldn't pinpoint exactly what worked.
1. Delete WDB and WTF folders in your WoW folder under program files. This (as I understand it) is where your client keeps all the cached information so now you're having to re-query from the server. This will eliminate all bad caches.
2. Second I attempted to log into another character on the same server.
3. I attempted to /reload ui
4. /script RetrieveCorpse()
5. These are the steps that actually worked: Run to the Spirit Healer and log out. Log into the other server (for me it was the PvE server). After this, I disabled all addons and logged back on. The Spirit Heals was spawned at this point. I re-ran the /script RetrieveCorpse() and /reload ui, ran to my corpse and was able to resurrect.
I feel like you won't have to do everything within number 5 for it work, but you can redo exactly what I did just to be safe. If I had a feeling, disabling all addons was probably the thing that did it, but I can't be 100% sure. Hope this helps someone else!
