Dealing with insane hangxiety

Spent the last couple days drunk basically and now feeling the withdrawals hit and insane hangxiety. I have GAD and panic disorder already and I just feel this horrible sense of impending doom, like I'm going to die. Don't need/want hospital, not puking, just feeling horrible mentally. Been hydrating, taking anxiety meds, had some yogurt and vitamin b complex. I know it will pass, I guess I'm just looking for some support in the moment on how to get through this
