Just found out my mum's step dad abused her as a child and I'm the result. I'm 33 and nobody told me till today. He had pschizophrenia. I've had mental health problems most my adult life and not one of my family thought to tell me it could be related. Coz he was mums step dad I always assumed his pschizophrenia wasn't an issue as he wasn't blood. Can I sue my family for withholding information vital to my health?
