The Archdiocese of Washington has a whole webpage devoted to the sacrament of confession. Here you can find everything you need to know about confession, which you might have forgotten. You can find a list of parishes and priests to go and unburden yourself to. It reminds us this is the season of Lent and that churches will be open on Wednesday evenings from 7:00 to 8:30 for confession.
I will admit to being a lapsed Catholic. I honestly could not tell you the last time I went to confession. It might have been when I was confirmed (as a teenager). Then again, I already expect to go to hell, the only question is whether I get to drive the train.
