Of corse she’s upset. Her career relied on a clown character she created that didn’t stand the test of time, toilet humor and incest jokes weren’t fun to start with but maybe suited her young self, definitely not a 35+ yo mother.
Her Joshleen relationship, albeit cheesy, had the spirit of young love, whereas her current partner is aloof, boring, mooching alcoholic- not exactly a person she can create content with.
And despite young children’s undeniable cuteness, her audience, predominantly tween girls, can’t give a s**t about family vlogging. She needs to reposition herself entirely if she wants to last on YouTube which is frankly her last “career” option… she can’t go into acting or singing because she doesn’t have the talent for it, maybe she can rebrand as music teacher, leave the public space and live her boring life, but nope, she’s so stuck to the spotlight she’s okay for the world to witness her low-grade depression daily rather than move on with grace and dignity.
I think she's getting worse because she's watching her friends be professionally successful, ie the Ariana and Jimmy Fallon song, that's more than just appearing on the show which she often slips into conversation to remind everyone. Meanwhile her life is losing its sequins and glitter. Colleen has to vlog every day or she'll lose relevance and that's such a trapped situation to be in. It's the only reason I can think for why she hasn't given herself maternity leave to heal and be with her children. People like Ariana don't have to vlog every day to keep their fans happy, they have a career and a separate personal life.
