You’ll need GM assistance since TBC Classic’s self-help “stuck character” web service seems to be AWOL.
Here’s the self-help support page for reference (or in case it starts working again). Click the “Burning Crusade Classic” button to see if it will help or not.

Anyway, posting in the forums won’t summon a GM to help, since GMs don’t take tasking from the forums. (Not even if you cleverly try @ing them.)
Unless the self-help service miraculously recovers, you’ll need a ticket.

Put in the specifics about your character’s situation in the form and explain the issue succinctly. Avoid editorializing or storytelling. You’ve already done it here and putting it into a ticket makes it harder for the GM to pick out the work they need to do.
Make sure to emphasize that self-help character unstuck for TBCC is not working so you have to turn to a GM for help. A GM’s first inclination will be to redirect you to self-help, so they probably need to be politely reminded that it’s not an option.
And then unfortunately, wait. Ticket response time is not good right now because of the added service burden of a new product with lots of bugs.
Good luck.
