My Paladin can't resurrect

I think I am currently experiencing a bug or glitch ...

I was levelling up my new paladin human and while being low level and having too many quests in my log and loads of random items + quest items in the bags - I end up losing the item "symbol of life", which was a REWARD from a previous quest from the chain.

See link for reference : https://classic.wowhead.com/item=6866/symbol-of-life

Losing that item put me in a position where I can't carry on with the quest chain. as the "symbol of life" is needed to resurrect an NPC, and only after you get to learn Redemption.

Would really appreciate any sort of advice here.

Should I make a new character? I am around lvl 55 atm - would be amazing if someone from the Warmane staff could send me the item - the item cant be sold or transferred and would not offer anything that would give me an advantage - without it I just have an incomplete paladin.

Thank you for taking the time to read this.

Looking forward to your response.
