下暗我真悿. 今仔日我真認真做空課
I am so tired tonight. I made a lot of efforts to do my homework.

下暗我真悿(tyam)。今仔日我真(今 zin)認真做( 仄 zè )功(gong)課(嗑 k)。

下暗我真悿(tyam)。今仔日我真(今 zin)認真寫(瞎 xia)功(gong)課(嗑 k)。

"zè" is ok, but we usually use "xia" in spoken Taiwanese.
我們台語都講"寫"。

我真'悿'? What's the word?

下暗(tonight)我真悿? I guess you meant you were being really happy, right?

I can uderstand his sentence of "今仔日我真認真做空課。" That means I did my homework very seriously today.
