First, God Bless you. I try to say a chaplet a day and I’ll remember you in that today.
Second, I’ve struggled with anxiety and anxiety induced depression all my life. I’m in my mid 40’s though.
If I might be so bold, what you’re experiencing isn’t unusual, and its okay.
I think we need to look at this two ways:
First, are you saying you’re having solid doubts? If that is the case, then I’d buckle down and do some reading. The amazing thing about Catholicism is that it has the goods in terms of reason and logic. Yes, you have to have faith; but it’s a reasonable faith. You aren’t asked to believe in Santa Clause or the tiny man in the refrigerator who turns off the light when you shut the door.Look into Peter Kreeft (his website has excellent talks and articles; www.peterkreeft.com). Listen to Dr. David Anders and check out ‘https://www.calledtocommunion.com/’. The Bible Christian Society is good as well. When I want to go old school I listen to ‘life is worth living’ by Archbishop Fulton Sheen.
There is alot out there; and it’s really interesting.
Secondly, you might be having spiritual dryness as well as, or in place of, doubts. In that case, rejoice! (seriously). You’ve been given a cross that many great saints have shouldered. Pray to God and ask him to help you carry the burden in the best way to glorify Him.
But also… and Dr. Anders covers this as well… don’t worry too much about it. We live in an era where alot of denominations have the praise band and the hands in the air and the weeping at services; and that is fine for those who feel those things. But it isn’t necessary. I’ve never been that person. And it makes me uncomfortable. People looked at me weird at a Steven Curtis Chapman concert because I wasn’t getting my praise on. But to me quietly praying in front of the Tabernacle is where it’s at. And that’s fine too. You can have an intellectual faith that doesn’t necessarily deeply touch your emotions. And for you that might be a more strongly rooted sense of faith.
Finally; to borrow a phrase from P90X (might be before your time) ‘keep pushing play’. As you age and go through life you’ll face difficulties and struggles; and your faith will wax and wane. And that’s normal. Sometimes you’ll be so full of the Holy Spirit its like magic. Sometimes you have to struggle and fight to say an Our Father, or even as I’ve done ‘Lord, I’m just not with it today. I’m empty and not feeling your Presence. Have Mercy on me, look into my heart, and help me’. If that’s all you can do, do it. But don’t give up.
