She's admitted speed, but not taken responsibility for it. No matter the state of her relationship, if you're looking after your kids does anyone with a brain think oh this is the way out of my problems. I'm guessing issues with James started after her escalating drug use.
Sounding like Mrs hinch here, but my sister had a short issue with speed, no idea why, but anyhow her house was always always a mess, a bad state. On speed it looked immaculate for a month, then she stopped, got fat again, and house is a ruin. Why was lou still in a mess, she could've done some manic cleaning stories.
