She's trying to manipulate you by the way. Don't fall for it.
Is this WW getting more desperate at this point? Do WW's act like this when things are not going their way? Is this the "It gets worse before it gets better" part?
Yes, it is "worse before it gets better" but because YOU will get better (you are! every step of the way) not because she will. Who knows why she's acting that way. Just shrug your shoulders and find something fun to do.
Your question sounds like you're inquiring if she's on the edge of changing. I think that's a way of trying to mindread or read the future. Your WW is acting terrible, so you should gently step aside while she is swinging her fists at everything around you. Do not get hit, do not engage.
