Ortiva is a colloquial term, particularly used in Argentina, that means 'grumpy', 'negative', or a 'buzzkill'. It's a more informal and expressive way to describe someone who is being a spoilsport or overly critical.
In the song, the artist uses it to acknowledge that his perspective might sound negative or 'ortiva' to some listeners, but he quickly follows it by saying his intention is actually positive. This word offers a glimpse into regional Spanish slang and adds a unique flavor to the lyrics.
Bhavi's "ANTIDEPRESIVO" is a really honest look at dealing with a breakup and the struggle to move on. He remembers all the promises, like "Te amo, yo quiero tener tus hijos" [I love you, I want to have your children], and how much it hurts to not fulfill them. It's like everything reminds him of his past relationship, and he's wondering how much more he can take.
He talks about feeling trapped and not free because he can't see this person, even having a dark thought about the terrace but deciding against it. But there's also a strong sense of hope and faith here. He keeps repeating "Ya se me pasará, ya se me pasará" [It will pass for me, it will pass for me] and "Lucho por fe, apunto al Edén, voy a llegar allá" [I fight by faith, I aim for Eden, I will get there]. It's a journey through pain but with a clear path towards healing and finding peace, even when life feels like it "apesta" [stinks] and you're getting a "cachetazo de realidad" [slap of reality].
