Just pray as you wish. All these novenas, liturgy of the hours, and other devotions are meant to faciliate our worship and understanding of God, not make it too formidable. So, if it doesn’t work for you, don’t go there – at least not 'til you’re more comfortable with things. There’s a lot of ritual in Catholicism because people tend to be ritualistic – from the times and ways we have our morning coffee/tea to the wedding rings that married people wear to many other things. The great thing about Catholicism is that there is so much to learn and grow with. The difficult thing about Catholicism is that there is so much to learn and grow with.
The main thing, as you are doing, is talking with God and attending mass. No matter what prayers or novenas or devotions one uses, nothing can beat the mass and reception of Jesus in the Eucharist! So, good for you!
I have found, over time, that the Rosary and Divine Mercey Chaplet are prayers that have helped me. I freely admit that there are days when I am distracted and pray these prayers with less than full attention and devotion. But take them as they come when they come.
Only one other prayer I would suggest, since things can be overwhelming at times, is the St. Michael Prayer, a prayer originally written by Pope Leo XIII after he experienced a particularly horrific vision of the future. The archangel is a good protector against the evil one. It’s a simple prayer, but an effective one:
St. Michael the Archangel, defend us in battle. Be our defense against the wickedness and snares of the Devil. May God rebuke him, we humbly pray, and do thou, O Prince of the heavenly hosts, by the power of God, thrust into hell Satan, and all the evil spirits, who prowl about the world seeking the ruin of souls. Amen.
Anyway, that’s my .02, for what it’s worth. I wish you a blessed holy week coming up and a wonderful, joyful Easter. Don’t let all the stuff overwhelm you. Just remember that God loves you immeasurably and wants nothing but the best for you. (Of course, when I tell my son this, he says, ‘yeah, right; then why is it so difficult a lot of the time?’ Sometimes we have to experience the rough times to grow, just like a plant needs to be trimmed back or even pulled out and transplanted to blossom with a nice shape and beautiful flowers. Sorry for rambling.)
