Fruits and Nuts: Leaf drop on Meyer Lemon bush, 1 by Takela

I have a Meyer Lemon bush and a Meyer Lemon tree. Both have been brought in for the winter. I have a sunny office window and the plants were doing very well. The bush had about 7 lemons ripening on it. Then I went on vacation. A co-worker was assigned to water my plants. When I returned I found some very thirsty, parched plants. My Lemon bush faired the worst of all the plants. Every leaf (with the execption of 5) was dry and crumpled. Merely brushing up against them caused them to fall off. My tree was very dry but the leaves have remained healthy. Is there possibly another cause for the radical leaf drop on the bush? Attached is a picture of the poor bush ... do you think it will survive??
