Try calling your parish office to schedule a confession or see if confession is available. It should be noted that if it is not possible for you to attend confession due to circumstances outside of your control (such as a very strict quarantine), you are not necessarily damned to eternal torment. The short article I’ll link below briefly sums up the Act of Perfect Contrition, because God knows that sometimes you can’t go to sacramental confession right at this moment. That said, sacramental confession is required before receiving the Eucharist, so hit it up as soon as you can!
Edit: Apparently I can’t post links, but if you google “Act of Perfect Contrition” it’s one of the first results, via America Needs Fatima
