If you are an A-type personality who likes to check things off your list, then you will want the accelerated course in "How to Grieve". I'm so sorry. I have not discovered this course. I'm sure it does not exist.
When you love someone, you risk the pain of losing them. I certainly understand why, in this fast-paced culture, you would want to get rid of such pain ASAP. But doesn't your loved one deserve this period of mourning? And don't you deserve this time to honor your feelings and reflect, however painfully, on the love that you shared?
Then there are others who do not want to leave the pain behind because they feel they are leaving their loved one behind. That is a myth—your love will continue always. Always. Your loss will eventually be assimilated into your life, your body, your heart. This happens softly, slowly, organically like watching a gradual dawning of the day. Please don't try to force it. Healthy healing occurs on its own timetable.
