My sister is in her late 40s she's divorced with 2 boys age 17 and 20 both at home. She got out of a long term relationship a year ago which ended badly and almost straight into a new one with a man she's known since school. This man has had major stints of heroin addiction since his late teens. He's been in prison multiple times and he's been disowned by his family..we were all gobsmacked when she started seeing him. Cut a long story short My sister has a good well paid job in the nhs and 2 lovely boys she's attractive and outgoing. In 9 months she's become a cocaine addict and alcoholic. She's neglecting her kids, she's drink driving on a daily basis. She's in thousands worth of debt, she doesn't hardly shower or clean her home, she's practically lost her job of 25 years amd she's not paying rent and bills cos she's buying cocaine. And she's allowing a smack head with a string of convictions to threaten her kids and chosing him over everything. As a family we've tried to intervene we've taken her to doctors for help and advise with addiction and we've offered countless support and advise. Its taken over our lives and started to affect our own families. She's so deep into this that her boys have gone to live with their dad, for safety and for their own mental health. I'm so scared she's going to end up dead and I don't know what to do anymore.
