Many things have to be done when a loved one passes away. You might not be prepared for this when the death is sudden, such as when a person is fatally injured in a car crash. When this happens, you have to find out what you need to do. One of the first things that you will need to do is to make the final arrangements for that person. At this point, it is easy to become so focused on what plans you are making that you might feel almost numb; however, that isn't going to last forever.
As you grieve, you are going to go through a range of emotions. These might be intense and come out of nowhere. Unfortunately, they aren't going to just magically stop one day. These feelings of sadness, anger and despair will continue --but they might slowly get less intense and less frequent.
It is imperative that you give yourself the time to deal with your feelings. Even if you are making the final arrangements and trying to just make it from one day to the next, you are going to have to think about your own mental health at some point.
One thing that you might decide to do is to seek compensation from the person who caused the accident that led to the death. This is a productive way that you can put your anger to use. It might eventually help you to get closure for the situation. Just make sure that you aren't relying solely on yourself for this. Instead, lean on your loved ones and get help from professionals so that you aren't the only one shouldering all of the responsibility and emotion.
