I got confirmed on Saturday in the morning. One of the people who prepared me to recieve the sacrament said that the mass would not cover my Sunday obligation so I went a few hours later at 5 o’clock mass. Before the 5 o’clock mass I debated whether or not to recieve communion because I had already taken it once that day and aren’t we not supposed to take it more than once a day? Am I in a state of mortal sin?
Unless you were searching for it to begin with, no. You described it as accidentally seeing it, and exiting it. Not a sin.
You need to take these concerns to a priest and avoid posting about them online. You need assistance beyond what can be provided here, and the internet is only likely to make things worse for you.
