I was the same. I took the time off, but judge for yourself which would work best for you. If being off looks like being home alone, then I'd avoid that until you've got some support practices in place, but don't be afraid to lean on your friends if you can.
Right now your only real concern needs to be getting through today & tomorrow in one piece.
There are other things that can/will help you later on, but right now you'll be in varying degrees of shock.
When it was me, I had the whole lot. Crying, tremors, blanking, raging anxiety, oscillating between occasional pragmatism/hope and pure black hole depression - to such a degree that I genuinely felt insane, including repeating thoughts of self harm (which was wildly out of character), the lot.
Things will start feeling better, and they'll probably start feeling better sooner than you can really believe right now.
But don't try to do it on your own, and don't give up. You're hurt, not broken, and you deserve support.
