I'm worried that my daughter is becoming an alcoholic. I'm finding empty bottles all over the house. Under beds, in drawers and backs of cupboards. She's recently been told to leave her college residence because of drink related problems. She drinks at every opportunity. To add to the problem I am not at home six nights out of seven. I look after my elderly father who has alzheimers and stay at his overnight. Three times recently i've gone home in the morning and there's been drink spilled on the carpet which i have had to clean up. I've let her know that i'm not happy but her attitude is, i'm a teenager, this is what teenagers do, get over it. I've told her i am going to take the key off her if it keeps happening, she threatens to leave and says i wont see her for a long time. Basically emotional blackmail. I'm constantly worrying about the situation, i dont know if i am right to threaten to take the key off her, if i will regret it if i do. She's 19 but has learning difficulties, i think she's probably has the mental age of a 16-17yr old. Me and her dad split up about 10yrs ago. She has 3 older siblings but they all live in different parts of the country. Any advice greatly appreciated
