Be honest. Tell the priest that it has been a long time since you have done confession, formally. Tell the priest whatever it is you wish to be absolved of (and be released from, whether, guilt, shame, anxiety,etc). You may be surprised at your experience. If you have a positive experience, you can go back for more. If you don't experience the support and understanding you need, then you might wish to seek counsel elsewhere. (Many Catholics haven't done formal confession for years, or even ever.)
