When someone we love dies our life is permanently changed. We miss the person because we loved them and depended on them for many important things. Frequently our pain is made greater because we have to learn to do many things that the deceased did for us, often times we don't even realize all of the ways a person touched our lives until they are gone. Raising children alone, earning a living, finding a job or a career, managing the household, finding new friends can all be difficult at a time when we're saddened by our loss.
It hurts because we must come to understand the impact that their absence will make, and this understanding will come slowly. For a while every day will bring small reminders, but with time there won't be so many reminders and you will learn to do many things on your own
Support from friends is most helpful. We can talk about our feelings with them and they can help us with some of the tasks that give us difficulty. This is a time to ask for help (or to offer it if you are a friend of someone who is grieving), people do not know what you need unless you tell them. Sometimes we need further information or assistance. At such times we should seek the help of professionals who can help us with specific problems we may have.
