i know they Psych evaluations seem pretty lax these days but I'd be amazed if they'd let somebody with diagnosed claustrophobia in there. She clearly hasn't got it, she wouldn'( be able to cope with that windowless bedroom, the diary Room or even concept that she can't just walk off the compound whenever she wants. She also wouldn't be able to cope with aeroplanes but i bet she jets off on fancy holidays several times a year.
She's just an attention seeking, lazy drama queen with no consideration for what effect her actions have on others.
