I grew up in a very dysfunctional family with abuse and was bullied mercilessly at school. I do however have a handful of good memories from childhood and I hold on to those. When I see kids today enjoying what I deem to be normal, happy childhoods I get a little sad but I remind myself that it's the past and I can't change it.
I have the present and hopefully a future to live and I don't want my past to rob me of that too. I hope you can come to peace with your past. It may come with time.
