我深知自己多么差劲
[wŏ shēn zhī zì jĭ duō me chā jìng]
A very candid and rather melancholy username where '我' (wǒ) means I/me/myself, '深知' (shēn zhī) conveys a meaning of deeply know or truly understand, and 差劲 (chà jìn) roughly translates to 'lousy' or terrible. All together, this could be translated into English as 'I deeply know how worthless/lousy/am awful I am' which may reflect an intense bout of low self-esteem.
