You can choose to stay angry, upset and sad, or you can choose to get on with life by facing what has hurt you and be content.
How many of us can do this effectively?
Most people dwell on what makes them unhappy without letting it go and getting on with their existence.
Dwelling on situations can sometimes make the hurt much greater than it really was, but if you can manage to talk about it with the person/s who has hurt you, then both parties will achieve satisfaction.
If you cannot accomplish discussion, for the sake of your happiness give consideration to, was it really that hurtful anyway!
