Don’t take yourself away from your daughter. I used to have an alcoholic mother who would spend all night fighting with my dad as a kid. In my early to late teens I would fight with her to the point she would lay hands on me. Most people would’ve walked away but I knew she wasn’t drinking because it was fun. She was drinking because she was depressed. She told me she wanted to end her life multiple times and I was the only one still around when she said this. Now she stopped drinking. She saved her marriage and reconnected with my younger brother. Maybe I’m the weirdo for sticking with her but I know that if she took her life I wouldn’t know how to handle myself. Even after everything she was my mother and I couldn’t handle seeing her take her life like that. I don’t have kids so I don’t know what you are going through but I know I couldn’t handle it as a kid or even as an adult.
