My youngest son was born in 1989. He needed heart surgery at 2 weeks to band artery. At age 3, they did open heart to patch a hole. 5 weeks later, a second open heart needed to patch 2 more holes. In died in 1994. I was prescribed anti depressants and benzodiazepines thru pregnancy. His dad did cocaine, methamphetamin, thc and alcohol. I have been blamed for his death. Also, my half sister died of hole in her heart in 1965 at 8 hrs old. Am I resposible for my son's death?
