I go to an Orthodox church where the entire congregation receives the Eucharist on a weekly basis. This was the same thing when I attended many Roman Catholic churches, and so I am familiar with the arguments for frequent communion, etc. However, when I went to RCC churches, I began the practice of not receiving communion unless I had been to confession first. I made it a rule to go to confession once a month.
I'm still used to going to confession before receiving Eucharist, but I understand that in Orthodox tradition (as in RCC tradition) one should not receive before first going to confession. It often happens that I cannot make weekly confession, and so I'm wondering: should I not go up with everyone else when it comes time for confession; or, should I go up, not stick out or appear proud or separate from the common unity that everyone else is expressing by partaking in the Eucharist, but yet risk drinking condemnation on myself? Thanks.
One cannot emphasize enough the point that Thomas makes - you should definitely speak with the priest about this issue. If it's important enough (it really is) that is may affect your path to salvation, then it's important enough for you to speak with the priest.
You can go up with everyone else and when you get to the chalice ask for a blessing instead of partaking in communion.
Hope that helps.
Anthony also brings up a good point that is often forgotten.
