I’m Irish but older than you, however I find IRE more ‘devout’ than any other country I have been to. I lived in Scotland, for 12 years, and religion is practically non-existent there, as compared to Dublin. My parish has 5 Sunday masses and they are all packed, with around 6 parishes to choose from, in my vicinity. So it’s all relative, I suppose.
However, I do agree with your sentiment, it is v difficult, if not impossible, to meet devout Catholics in day to day life, at jobs, socialising, etc.
Possibly, you could volunteer to help with an overseas pilgrimage, e.g. to Lourdes/Medjugorje, as many young people sign up to help with invalids/sick people that need assistance, and if from IRE you could meet up with them on your return.
Also, I note there are many young people assisting with the Prolife movement, at present, putting up posters, canvassing, etc… in relation to the 8th amendment referendum. I think offering to volunteer with a group, with a Catholic ethos, would be your best and speediest option.
(E.G. Prolife is currently crying out for volunteers, to canvass, etc… for the last 2 weeks of the campaign.)
