Hi,
If you feel suicidal you need to dial 911...
If you can get over that then you still probably need to see a Dr. Asap.
I understand about worry about your job. At least you are not drunk. That is a major win.
Now you have tons of anxiety. Eat, drink water, take multi vit., vit b12 sup, omega 3...rest...repeat...
My anxiety got way better...a little better every day...or so...right now it is almost gone...
What you feel is likely normal....but you are missing the mind altering effects of the booze...
You probably are not going crazy...
