It takes the time that it takes
You do not have to conform to a set time to grieve or get over something. It takes the time that it takes. It takes more time for some, less for others. It is not a race. It is important to take the time that you need to process what has happened. If it takes you a little longer or a little shorter time than someone else, that does not make either of you right or wrong. Take the time you need.
