Diabética literally means "diabetic". It's a highly unusual and striking word to find in a love song, making it instantly memorable.
In the lyrics, Don Omar sings, "Otros amores del pasado me han dejado diabética y no puedo ser dulce contigo" (Other past loves have left me diabetic, and I can't be sweet with you). He uses this metaphor to express how past heartbreaks have made him emotionally guarded and unable to be tender or vulnerable in a new relationship. This creative and unexpected use of the word adds a unique layer of meaning to the song.
This song is a back-and-forth between two people who are falling for each other but are terrified of getting hurt again. Natti Natasha kicks it off by saying she swore off love and Cupid's games, but now this guy has shown up and they're "Hablando de amar" [Talking about love]. She's been burned before, and she has one of the best lines about it: "Otros amores del pasado me han dejado diabetica / Y no puedo ser dulce contigo" [Other past loves have left me diabetic / And I can't be sweet with you]. She's scared he'll sell her a dream and then leave her for his main girl, saying if it happens again, "me muero" [I'll die].
Don Omar's response is all about trying to convince her he's different. He admits he also promised he wouldn't believe in love anymore, but she's changed that. He tells her that even though "El pasado a sido duro" [The past has been hard], he's pretty sure he can change things for her. He's completely captivated by the way she dances and kisses, and he can't get her out of his head. The chorus sums up their shared dilemma perfectly: "Me gustas pero tengo miedo de fallar en el amor" [I like you but I'm afraid to fail in love]. It's a classic story of two guarded hearts finding it hard to resist a new connection.
