I think one of the points brought up is that the Latin is distracting the OP from their prayers, rather than enhancing them. It’s up to the OP to determine where the trouble is coming from. Latin is a beautiful language, and since it’s been adopted as the official Church language, it’s a holy language as well. Exorcists will be the first to tell you that prayers in Latin have a certain impact that prayers in the vernacular cannot duplicate.
It’s ultimately up to the OP to determine why praying in Latin is distracting for them, and I think that a number of posters have done a good job of offering different theories for the OP to consider.
Latin’s also a hard language. I’m probably preaching to the choir, considering the subforum, but it bears pointing out.

For example, depending on the gender and plurality of the noun it modifies and its place in speech (since Latin has no word order), there are 90 different possible ways to decline an adjective. You can’t just have a “blue” something; the word for “blue” will change depending on whether “blue” modifies a feminine, masculine, or neuter noun; whether it’s a singular or plural object; and whether you’re dealing with the subject, direct object, indirect object, or whatever. I think those sorts of things are what previous posters might have been addressing— if your fluency isn’t quite up to par so that you’re able to freely pray, it’s very easy to get bogged down in declensions and conjugations.

Of course, a rigid prayer like the “Our Father” or “Hail Mary” is going to be different from a freeflowing conversation with God, but the point remains that a familiar prayer in an unfamiliar language might pose an obstacle when we’re supposed to be conversing with God and meditating on something better than grammar.

Praying in Latin is a nice way to familiarize yourself with a single prayer, but regular study sessions with Wheelock’s or Miller’s are far more helpful to familiarize yourself with grammar and the language itself.
