help my plant is about dead

You might want to consider taking 5"-7" cuttings if you have any vines that are still healthy, then you can try rooting the bare one inch ends of the stems in a small pot with good draining soil.You can also try rooting those white bulbs by placing them a little less than halfway down into the soil like an amaryllis bulb, in time they will sprout new vines and leaves.

Care for "string of hearts" (Ceropegia woodii) Bright indirect light, water when pretty close to dry. With more mature plants, keep roots on the pot-bound side in a pot that's not much bigger than the root-mass/root-ball.
