If you're depressed over the loss of your aunt then that is normal. If you are or think you might become dysfunctional over it then you should talk with someone. If you are very agitated or lethargic or can't sleep then you should see a doctor to help that until you are better. If you've been depressed in the past then you should see a doctor now.
Did you know there are only 5000 Snow Leopards in the wild now and they are confined to Central Asia? However, the effective global population (those likely to reproduce) is less than half that number.
