As for Rosary beads, there are many who say they’re helpful. So I’d say try using the beads if you have them handy. If not, that’s okay too.
As for praying in your own words, yes, God wants to hear from you! As my grandma once put it in her enthusiastic Irish way, “Pray like God is everyone in the world who LOVES YOU !!!”
Sometimes I can get real silly while praying in the Adoration Chapel, like walking in and noticing the color of the glass candle covers that match the liturgical time of year. For some reason, they remind my imaginative mind of Kool-aid flavors! So I walk in and pray, "Oh Jesus, you look SO BEAUTIFUL surrounded by lime green Kool-aid candles! (or cherry red, or grape, you get the idea … ) :o And then I pray about how Jesus in the Eucharist surrounded by candles is the Light of the World and doesn’t really need all our tiny little flames, but that God the Father must smile down on the priests or altar servers who light them in order to please Him.
