So, I've had a history of eating disorders, and it's only fairly recently (say, within the last year or so) that I've been able to eat somewhat normally. I no longer count calories meticulously and am maintaining a healthy weight.
So, I gave up sweets for Lent, just because I've always had a huge sweet tooth.
In the wee hours of this morning, since it's Sunday, I ended up eating way more sweets than I should have. I calculated out how many calories I had snacked on total... way too many.
In examinations of conscience that I'd read (like the Mea Culpa app or the examination of conscience on the Catholic Culture site, gluttony/overeating was usually labeled as a "venial sin," so I did not think that it was grave matter. However, after reading someone's post here on CatholicAnswers about gluttony, I begin to wonder if I sinned mortally.
"When do they become mortal? Well if you willingly reject God for pursuit of a worldly pleasure instead that would be setting yourself on the path to a spiritual death. What that point is is up to each person to decide." (from this thread)
I know that a mortal sin is mortal if it is committed with full knowledge, which I don't think I had since I did not think overeating was grave matter.
Knowing that I ate way too much in the wee hours, I have decided to fast (just drinking juice and other fluids) for the rest of the day, allowing what I ate this morning to sustain me throughout the day.
Could you all please help me out/give me your opinions on the situation? I'm extremely vexed, as I attend Mass at 6pm and would like to receive Holy Communion.
