Once you realize you are grieving, take notice of what it is you grieve, then recognize that it is over and start each day anew, knowing that God can make this hurt go away and turn the bad into good. It is said that grief must be dealt with in stages, and not necessarily in the same order every time. Many people feel the guilt first. Then she gets angry for the same reason. These are still two aspects of grief that can happen simultaneously.
Some people can go through the grieving process very quickly.
Breaking up with a boyfriend or girlfriend who dumped you for no good reason would probably fall into this category. YES, this is a grieving situation. People grieve over a loss. People who lose their hearing or sight must go through all the stages of grief. Some people, especially those who do not know the Lord and His comfort never get to the acceptance stage.
