Put Lickorish in a nice quiet room with the door closed at mealtimes. You can stay with her if you like. I would leave the food down for about a half hour, and leave after 5 or 6 minutes of petting to reassure her. If she's still not done when I got back, I'd take the food up, and either put it away for the next meal or throw it out. I would definitely keep it away from the other cat. Not all cats can eat together in the same room even with supervision.
I have 4 cats and they have to be separated at mealtimes. 2 go at a time; 1 in the kitchen and the other in the bathroom and then they switch. They are so used to it now; it's like clockwork.
You should check Lickorish's body condition. Can you see her ribs? If so, then she is definitely underweight. You can also view:
