I have not followed the teachings of the church until recently and I had not been to confession more than a few times since my first confession 40 years ago. I tend to get very nervous. I went to confession Saturday and as most of the priests I have received confession from lately do not pause between the penance and the absolution I was focused on getting the Act of Contrition in there and I realized on my way home that I had forgotten what the priest gave me for penance. I decided to say one Mystery of the Rosary, clean my apartment, and fast, skipping dinner and not eating until Sunday morning as penance. I thought that should more then cover it compared to what the priests normally give for penance. I asked God to forgive my over site and said an Act of Contrition. I went to Mass Sunday and received communion. Now I feel guilty that I sinned by taking it upon myself to impose a penance and by receiving communion. Was this a sin? Do I need to confess the self imposed penance and receiving communion before I can receive communion again?
Thank You ,
