翻譯我衰左三年我等一個機會掙返口氣唔係要證明話比人聽我威只係想話比人聽我唔見左既野我想自己攞返什麼意思

我衰左三年 我等一個機會掙返口氣 Not having had a good run for three years, I've been waiting for a chance to catch my breath.

唔係要證明話比人聽我威 Not to prove to anyone that I'm great,

只係想話比人聽我唔見左既野我想自己攞返 I just want to show people that the things I've lost, I want to get back for myself.

什麼意思 What does this mean?
