You can help your cherry tree settle in by making sure it is getting enough water. If Mother Nature doesn't provide it with a soaking rain once a week (1 to 2 inches), you are going to have to pitch in and help. Five to ten gallons of water once a week should be sufficient for most young trees.
To help conserve moisture, extend a layer of mulch 3-4 inches thick, out 6 to 8 inches from the trunk (leave at least 1 inch of space between the mulch and the trunk). Skip fertilizing until next season.
As long as your weeping cherry still has leaves (even small leaves that appear to be in limbo), your tree will likely recover just fine. You may even see a few lost leaves before it's all over.
If you start to see significant leaf loss, you might want to contact the nursery where you purchased it and inquire about their replacement policy. It's also a good idea to keep your receipts and document the tree's appearance with a few photos.
