我只是个烂人不怪你不懂
[wŏ zhĭ shì gè làn rén bù guài nĭ bù dŏng]
This can be translated as 'I'm just a terrible/worthless person, don't blame you for not understanding me'. A holder of such a name may feel disappointed with himself/herself for various failures or wrong doings he/she has made and does not want to put any blames on others even when others fail to empathize or understand.
