Hello Drisgirl. What a terrible story you have told, and of course I can only offer my sympathy to you and your family.
Where can you find a well of strength for your children when you are so emotionally drained already? You want to be strong for them, and yes, it is understandable that you should be full of anger at the prospect of a forthconming trial.
Yet, life has a funny way of payback, and if you will listen to my advice, it is this. You should try and distance yourself from the outcome of the trial and let the wheels of justice turn in their own time. This woman has more to lose than her licence. Her conscience will prick her for a long time to come. You must not feel the need for revenge, as that will only backfire on you and your children.
Only by accepting what has happened and grieving for your losses, will you come through this. You will never be the same of course. Every bereavement leaves its scars on us, and although they fade, they never go away.
Forgiveness is as much for your benefit as for the benefit of the wrongdoer. It lances out the poison from the soul, and allows the healing to begin.
So, yes, shout and scream on here, and get rid of your anger, then look outside of yourself, and accept what you cannot change, and there you will find the beginnings of strength.
