Her biggest problem, aside from being stupid, is that the two most sure-fire cures for her malaise are out of reach to her. If she had a job, she wouldn't have time to police YouTube for 7 hour stretches (and then shut off comments, making those 7 hours a complete waste of time), she'd have a normal sleep schedule, and she couldn't constantly eat.
Unfortunately, she is too fat, lazy, and incompetent to get any kind of job.
Her other alternative would be to exercise more. But she is too fat for that too; she can't walk five steps without getting winded. That's too bad because some exercise and time spent outdoors would surely refresh the mind and body.
So she is trapped. Friendless, she must turn to YouTube for her social life (and just like everywhere else, people there generally dislike her). In a lot of ways, she is worse off than Amberlynn, who at least has her dopey friends; dum-dums are better than no friends at all.
Chantal, if you are out there, this is not the road to Mt. Everest...
Honestly, I don't see a long life ahead of her. I see medical issues compounded by her own neglect, mental issues that may incapacitate her completely (not far to go), and a miserable existence locked up in her fetid apartment until the ambulance comes. Sometimes I even think (not gleefully) that she is a potential suicide in the making; the day may come when she fucks up so much she just deletes her whole life.
