You are right, there is no closure.
I am ready the most amazing book right now "Letting Go".
It is about surrendering yourself and emotions. Everything comes from certain emotions. These must be recognized and understood what has caused you to get to these emotions. Feel it, understand it, and the you will be able to let it go forever. Instead most suppress it and think that is normal. In these circumstances, the emotion and hardship from it can last a life time.
