孤独久了碰到幸福都会恐慌冰握久了碰到冷水都会暖手
[gū dú jiŭ le pèng dào xìng fú dōu huì kŏng huāng bīng wò jiŭ le pèng dào lĕng shuĭ dōu huì nuăn shŏu]
This nickname expresses feelings of being accustomed to solitude and isolation for a long time, such that sudden happiness or warmth feels unfamiliar and overwhelming. It reflects the emotional contrast between a person who has felt 'cold' (alone) and the impact of a relatively 'warm' (happier, less lonely) situation.
