我自己已经身患绝症能解你病的药只有你
[wŏ zì jĭ yĭ jīng shēn huàn jué zhèng néng jiĕ nĭ bìng de yào zhĭ yŏu nĭ]
Translated directly it means 'I am terminally ill myself; but you are the only medicine that can cure you.' The user implies they cannot help themselves but are willing or hopeful that their presence brings benefit and joy to someone.
