Judia comes from the verb judia(r), which means to torment, abuse, or mistreat. It's a strong and somewhat dramatic word that you don't hear in everyday conversation as often as more common verbs for suffering.
In the song, the lyric "Mas judia da gente" (But it torments us) refers to how love, despite not killing, can cause immense emotional pain and suffering. This word choice adds a layer of intensity to the feeling of heartbreak described in the song.
"Dessa Vez" ("This Time") is a Brazilian pop song about giving in to love after trying to fight it.
The singer admits he tried to stay away, telling himself he didn't want to call or see this person again. But the distance only makes things worse. He's scared, he can't sleep, and he's tired of hiding how much he misses her.
By the chorus he stops pretending. He asks her to come back, and this time, instead of running from his feelings, he surrenders to them completely.
It's a simple, heartfelt song about swallowing your pride and admitting you still love someone.
