Hello, It usually take weeks or few month to get adjusted when you go through a breakup. You have tried your best in this relationship so do not blame yourself. If the sadness prevails even after that then you need to consult a neuropsychiatric center. If along with sadness you are having loss of interest in previous pleasurable activity, feeling lonely, change in appetite and sleep, low in energy, confidence, hopeless, helpless, worthless feeling and sometime even suicidal ideas. Then you might have depression. Few of these symptoms or all can be present at a time.
