If you just did it yesterday then it was too soon to know if it died or not. It is normal for them to look wilty and droopy for 3-4 days.

Take a 4-6" growing tip, remove all but the top leaves, insert the bare stem deeply into container of damp potting mix burying most all the stem, lightly compress the damp mix around the stem, water well, set the container out of the wind and direct sun.

Keep the soil in the container moist. Once the cutting stands up on its own and new growth appears water as you would normally and give it 10 days to two weeks to develop roots before transplanting to the garden.

That's how I do it and have done hundreds that way over the years.
