The first step would be finding a denomination and Church that makes you feel like you're at home. If you'd like to stick with Catholicism, visit several different Catholic Churches and see how you like them. If you're interested in exploring other denominations, go to several different of each Lutheran, Methodist, Episcopalian, Baptist. You can't always get a feel for a denomination just by going to one Church.
I've had an interesting faith journey. I was raised Lutheran. I went to a Lutheran school, was confirmed, and felt very strong in my faith. In my teens, after my brother died, my family basically stopped going to Church. I didn't practice my faith for years. When I got married to a non-practicing Catholic, and had my first child, things changed. I wanted to raise my kids in the Church. I had my daughter baptized at my Lutheran Church and just expected my husband to start attending services there. He wasn't interested and told me he'd go to Church if it was a Catholic Church. I somewhat hesitantly agreed as long as he was committed to going. We found a Catholic Church in our area and started attending. As a non-Catholic, I couldn't participate in the Eucharist, but I participated in everything else. I came to really, really love going to mass and felt at home there. After 2-3 years of attending as a visitor, I decided to go through the RCIA program (Rite of Christian Initiation for Adults) and became Catholic the following Easter at the Easter Vigil. It was one of the most special nights of my life. Since then, my life has been enriched by the Catholic Church. My children attend the parish school. My second and third babies were baptized Catholic, and my eldest made a profession of faith and received her first communion in second grade with her classmates. I am thrilled that we are all the same faith and attend and participate in mass together as a family.
Prayer is conversation with God. I pray throughout the day. I usually pray for patience and understanding with my kids, the health and safety of my family, friends, and even strangers if I hear about something on the news, or see an accident while driving. I do dedicate special time before bed to pray as well. I pray during mass. I pray both the traditional prayers of the Church as well as stream of consciousness prayers. Both forms of prayer bring me peace.
As for Bibles, I have a Catholic Study Bible that I love. It has side captions with explanations of things that are hard to understand. A good study Bible seems like it would be a great fit for you. You do not have to read it in order.
Group Bible studies usually focus on one book of the Bible or a theme that encompasses several passages. You usually read it on your own ahead of time, reflect on it, then come to class prepared to discuss and share your thoughts with the group. I don't participate in one now, but I have in the past. Some have been better than others depending on the leader and other participants. It's about finding a good fit whether it's a Church or Bible study.
Best wishes!
