Really unfortunate notice situation

Hi again r/jobs, I posted previously about not wanting to give notice during the holidays and giving my employer some additional time with the transition.

Well, I just found out today I've been given a 15% raise at the job I'm leaving. This has become a nightmare situation. How am I supposed to give my notice now?

What do I do?? I don't want to stay at this job and am supposed to start my new job the 4th.
