Consider it God’s will
You must remember that every single creature in this universe has to taste death sooner or later. If one of your parents has died, consider it God’s will, and find peace in this belief. Make sure the event does not adversely affect your professional or personal life; remember that life has to move on at any cost, even if you have just faced an unbearable loss.
Avoid going into depression
A parent’s death can send even the strongest, most stoic individual into a crippling bout of depression. However, you must show strength of character at this difficult phase of your life, and not let the circumstance break you from the inside.
Console your siblings and other parent
One of the worst attitudes that people can adopt in such circumstances is to behave selfishly. If you have brothers and sisters, and if your other parent is still living, remember that they are all going through the same emotional pain you are suffering, and that they require your moral support. Your family has to be your utmost priority at this stage, and consoling them should be far more important than indulging in your own grief.
Pray for the soul of your deceased parent
Pray to God for the soul of your deceased parent, and ask others to do the same. Try to visit the grave of your parent regularly, at least once a week, as this activity will grant you inner peace.
Do not forcefully stop your tears
Allowing your tears to flow freely will help you feel relieved and relaxed. Do not stop yourself from crying if you really want to, as this will only lead to repression and could make you mentally and/or physically ill.
