How do I say "I struggle and emerge" in Mandarin?

我奮鬥後重生
It means I reborn and became a better person after fighting my hardest.

If you want the word struggle, it would be 掙紮 and replace 奮鬥.
It is a bit weird to use 浮現, it means appear. It usually uses with the word truth 真相, or true color 真面目.

First be sure that it is understood in English. I find it hard to understand what you mean. Do you mean that you have made great efforts and have now come out of your time of difficulty?

Simply translating word for word might look very odd in another language.

Hi..I will show you the pinyin of it ..The Mandarin of it is wǒ zhēng zhá zhě chū xiàn（我挣扎着出现）。
