I couldn't read this without feeling the urge to say 'something'. But I honestly don't know what to say. I am sorry. Sorry for all the suffering and the lost childhood as well as the missing normality you are still struggling with. I hope you will be able to work through this with time and some official help, but after reading this I have to say: I have no idea at all what this must be like. Just wishing for the best outcome possible for you.
