I am trying to get back in to the catholic church but I realised that I have made a grave mistake taking communion even though I haven’t confessed in more than 20 years. I did confess once when I was much younger but I can’t remember the whole process of confession.
But each time I want to go to confession I have this guilty feeling and I don’t know why.
Also I have trouble remembering how many mortal sins I have committed and how many times I have committed them.
Can any one help me with this?
