It's Sheba, Darth, and it's a very simple word, simpler than Wookieeism even. (Why, by the way, are you using your inability to copy paste two syllables as an implication that I'm the idiot?)
Trichotillomania is a recognised, though little known, OCD condition that is indeed diagnosed by behaviours such as pulling, chewing, biting, playing with and even eating hair and its roots. (And sufferers' hair is often long and straggly because they're too embarrassed to go to the hairdresser for fear of being derided for their 'gross habit'.) This woman has trich. It is clear to anyone who knows about the condition (I do), and as I said, the only voice that should be silenced in a discussion about it is a rather hateful one who didn't even know it existed until a couple of hours ago, which would definitely include yours. Habit is indeed often formed around OCD and addiction, but true addictive urge still remains under that and usually needs therapy to be managed. Again, most people are capable of realising this.
Is trich disgusting? Yes. So is inducing vomiting, but we do mostly understand that bulimia is a real medical condition.
And most of us also understand that we are not familiar with every condition in the medical dictionary. So when someone who has many years of experience with one that's new to us explains what these symptoms do in fact diagnose, most of us would have the decency, even if we don't have the intelligence, to accept that it is a little more complicated than just a 'gross habit'.
Then again, most of us are not Sith Lords unable to learn two-syllable names, so perhaps I am indeed expecting too much of you. Are you going to get over yourself and try to use your new knowledge to better yourself? Do, or do not. There is no try.
