我矫情做作没她善良我犯贱淫荡没心没肺
[wŏ jiăo qíng zuò zuò méi tā shàn liáng wŏ fàn jiàn yín dàng méi xīn méi fèi]
It translates to 'I am pretentious and less kind than her; I am unworthy, promiscuous, and devoid of emotion,' revealing an extreme negative self-perception and possibly jealousy toward another person who the user considers to be better than themselves.
