I am sorry Lucy is so upset.She is probably reacting to all the anxious energy in the house.
Cats do not follow a pack leader the way dogs do but they do sense their human parents energy and respond accordingly - so if you are nervous, they will be nervous. If you are stressed, they are stressed as well.
make a cheap safe mood stabilizer add 3 mg of melatonin to food containing turkey. Either baby food or canned cat food.Turkey contains l.triptophan so combining it with melatonin will calm her down. However it must be given every 24 hours as the effects are cumulative.
There are several othe things you can do. Play a radio softly at night so she does not "hear" so much quiet. Leave a soft light on so she does not "see" so much darkness. Get some feliway plugins as these will calm her down, she can get very anxious at night. You can get them at some pet supplies or http://www.catfaeries.com/
Please let me know how she is doing. Just reply here or if you prefer, we can speak on the phone.
