My son got hit by a car when he was 9 in our little village when crossing the road from school I was over the road and saw it happen even though I tried to shout him that there was a car coming the other way as another driver let him cross, he wasn’t hurt as the driver that hit him was going slow he hit the bonnet. He is now 12 and I still feel like the worst mum ever like this doesn’t happen to normal mums and the constant regret of letting him cross the road. How can I get rid of this feeling of constantly wanting to make up for it.
