Quoted By:
Dads, Beatani keeps hinting at being depressed and questioning her life while also saying she has no energy nor will to do much other than getting into her futon, drinking water and streaming.
It's visible that dads make her day better, but dads are only on a screen. As soon as she looks away from a screen she is back to her life.
What would cause her depression?
Feeling alone could make someone depressed, but she has friends she could meet, and if it's the "no partner" alone, it's hard to say, because she shows herself at least to us as someone uninterested in romantic relationships.
If it's her routine, she is stuck in a loop where anything that could change her routine to something more interesting (exercise, reps, editing and preparing new music, etc) is met with a "mendokusai" or just skipped by her getting drunk, being cynical, or going to sleep.
Her enviroment might affect her if she is living amongst trash from her dirty room.
It's worth nothing that bathing every day is an improvement towards her daily routine.
TL;DR: I have illustrated Beatani's vicious cycle.
