Have finally caught up, it doesn't pay in the long run to go to bed does it.
I really hope that stuff is going on in the background that will help them all. IG and the girls are probably scared if not terrified of her rages having experienced them for many years. I think most of the people who have had her best interests at heart eg friends, kind hearted strangers and celebs etc have now deserted her, you cannot reason with 'crazy.' She is coming across as psychotic/manic at times and needs proper psychiatric intervention now. Her brain and body seem to be totally wired, lack of sleep, eating crap, high cortisol stress levels, high alcohol and drug consumption are definitely taking their toll on her.
Her lackeys are encouraging her mania and breakdown, that is not about care and friendship, that is them getting a high from her histronics. She needs to go to an inpatient facility, he needs to collect the girls and try to rebuild a relationship with them. When she's stable then have joint custody of them, I'm sure she loves them and has some mothering capabilities beneath all of this horrible mess.
Her only 'crusade' at the moment is her own destruction of self. She is too fragile and wired to listen to reason. She needs professional help and no matter what has happened between them, I hope IG has enough compassion for her and his daughters to get her the help she needs.
