Please consider how lucky and blessed you are to be able to go to confession at all! I haven't been in 13 years, and cannot because I am divorced and remarried, and after years of trying, an annulment is not obtainable for me.
I didn't think I'd ever miss confession - the Eucharist, yes, but confession? 13 years later I'd give anything to be able to go and hear those wonderful words of absolution...
So please, pray for courage, and it will be given to you, and then just GO, and please say a prayer for me, too.
Peace,
Elizabeth
