I don't think she can be all alone by herself for any length of time. She literally said at one point that she can't sit down and just read a book from beginning to end. My impression of her and the way she talks on her Livestreams or in DMs is that she has to be in a constant interactive loop with someone or something. She can't just shut her down her thoughts and listen to someone else's expression, or try and relate to their reality, which is what book reading is. You can write your own thoughts in the margins but you're basically listening to someone else's story. She can't do that. All of this is reinforced by her actively damaging her own brain, through vaping, drug abuse, aimless online procrastination, bad eating habits, her regular drugs. She's never not busy hurting her already malfunctioning brain.
