My father is an alcoholic, he lost his job due to alcohol, and every day all he does is drink and drink. My mum doesn't work, but she's been put under severe stress. My father constantly shouts at her and refuses to stop drinking - he has no care for his family. This is not an environment suitable for my sister - can this be a reason to take custody of my sister- I want to move out of my parent's house and away from that environment, its too damaging.
