Well, to be honest there’s not much other than the priesthood, lay single hood, or married life, unless you’re going to become a religious! You’ve just about ticked all the boxes before you even make a start.
I gather you’re the ripe old age of 20. While concerns about the tuture seem important to people of your age, God is eternal. Another couple of years won’t make much difference to Him.
I remember when I was a new Christian, and asking the same question viz. “What am I supposed to do, and how do I find out?” I asked one of the pastor’s sons (I was Presbyterian then…) and his reply wasn’t exactly what I wanted to hear, which was -
“You might be waiting a long time. Moses was 80 before he was called.” Much as I didn’t like to hear it, he was right. And I doubt if Moses wanted to spend 40 years out in the backside of the desert of Midian as a shepherd, or another 40 years shepherding a bunch of complaining Jews through another desert. But that’s what he ended up doing. One thing was certain - it wasn’t HIS plan.
I think you might need to develop a bit of patience. Now no doubt you made a decision to study IT, and it seems you’re doing fairly well at it. So while you had a hand in making that decision, in another sense God put you there, and until He makes it clear what He wants you to do, I think you’ll find He expects you to stay there.
You don’t know - an opening might come up while you do your studies. Moses was just doing his boring job minding a bunch of sheep when a burning bush caught his eye. The rest is history.
But if you wander off and make your own decison without reference to Him, you can cause yourself a lot of grief. No doubt you won’t see a burning bush (unless you’ve got a flammable screen saver, as in one hilarious episode of “The IT Crowd”), but you know what I’m getting at.
So if I were you, for the time being at least, i’d just complete your course of study, get a job, even if you don’t like it much, and wait for God to make your paths clear. It’s not always easy, but patience is a part of faith.
Just stay where you are until you get some sort of divine guidance. And when you do, you’ll probably find it comes through another Christian, preferably Catholic Christian in your case.
