Without negating the fact that she is a terrible human being and needs to be the centre of attention, I feel the reason she hasn’t stayed friends with other people with an online presence is because she’s too insecure to appear in their vlogs/ pictures which she doesn’t have control over, she can’t edit or carefully select the angles.
The reason she doesn’t like YouTube and now hides behind her “sew smol business” and food videos is so she doesn’t have to appear on camera.
The sad part is if she was just herself from the beginning and didn’t manipulate her content to make herself look completely different she wouldn’t feel so bad about it.
I just remember certain instances when (I think it was) Casper filming her eating and she was very unhappy about it!
