That's okay, Mary. I understand. I will do my best to help.
It is good that it is still in its nursery pot. That means you don't have to worry about overwatering it. The leaf loss is probably due to not enough light or not enough water or both.
Keep it in your sunniest indoor location right in front of an uncovered window. Water it as soon as the top surface of the soil feels dry. Always pour the water in slowly until some drains through the drain holes. It is important that all of the soil is completely saturated after you water. Usually, a through weekly watering is about right. But if in doubt it is better to water rather than to delay.
It may take a couple of weeks before the leaf drop stops so be patient.
