I know how you would be feeling on the sudden demise of your dear daughter. She was a sweet and charming little girl, who was always able to bring a smile on my face. May her soul rest in peace.
The best way to remember someone it to do it with a smile on your face. You will not be able to do it soon but at least try and this will make the soul of the one who has gone happy.
May you get the strength to handle the situation in the best way possible. Your dad was a great human and I am sure that was the most wonderful dad in this world. However, at this time it is important that you help you family come over with the situation, so that you can make him proud.
We will pray for you and your family. God has a reason to all that he does, may be this time he decided for your mom so that she can take rest however, she will always be a part of our thoughts and will be cherished in our heart.
