You also asked can abortion be forgiven.
Abortion is a grave sin as it is the killing of an innocent and defenseless human being.
However, this sin can be forgiven through the Sacrament of Penance provided that the person is truly sorry and genuinely seeks God's forgiveness. I hope that you will return to Confession. You do not need to be afraid of talking to a priest. Any priest will be happy to assist you, especially since you have been away for a number of years. I will pray that you will receive the grace and courage to come back to Confession.
