Most of the stuff she comes out with is EXACTLY the kind of stuff a 14 year old would say, which is probably why she still has a small fanbase of teenagers. She's never grown out of that mental age.
It's all 'I'm not close with my family, I never had this as a kid, I'm sew sew ill guys send me messages wishing me well, look how many people sent me presents for my birthday, getting therapy is SEW SEW scary and the therapist was MEAN, I want to design bedrooms but not be a set designer, I'm sew niche, I can't wait to have a perfect life with cute kids in matching outfits and a cute forever home when I'm older, I'm going to TREAT MYSELF and have [insert whatever unhealthy snack here 5 times a day], this person is my BEST BEST friend, I'm being BULLIED, I can't wait to show my bullies how successful I am now'
The posting on social media before thinking and having to delete it later is also a classic early teen thing to do, since they often haven't matured enough to learn consequences for their actions.
