Uh, Lizzo references? I don't really like Lizzo either but at least she's an actual celebrity and Tess trying to compare herself to Lizzo seems like reverse projection or her trying to be a sassy black woman again.
Also, at this point she needs to just have her kids taken from her. She's basically the definition of an unfit parent and the best possible thing for them is to be removed from her house. She could try to play the victim of course, but it's so rare for mothers to lose custody entirely that nobody would take her seriously if she claimed she was being persecuted. She doesn't even seem to want to be a parent. I honestly don't even know if she has her kids more than half the time anymore. I don't give a shit that she's going through a divorce and wants to live her life and 'detox' or whatever. You become a parent, your kids come first, always, until they're 18.
