I’ll give you an anecdote from my own life. Sometimes I just feel overwhelmed by the faith (I’m a new Catholic, just baptized/confirmed at Easter 2015). I try to pray the Rosary every night, but there have been times where I just wasn’t feeling it. I didn’t want to do it, I didn’t think it made any difference, I didn’t think anyone was listening. And so I just started talking to Our Lady and told her that I hoped she wouldn’t be mad but that I wasn’t going to pray the Rosary that night. I found myself just pouring my heart out to her- all my frustrations, all my fears, all my hopelessness, and found myself crying. And when I was done, I prayed the Rosary and felt better.
Don’t be afraid to just tell Mary how lost you feel. She will take that to our Lord and will intercede for you.
