I think father in this case means Heavenly Father.Jamie has had an abortion, she's churned up with emotions inside (torn inside) and, although she puts a good face on things, feels very guilty because she was brought up being taught that abortion is a sin and when you sin God turns his face away from you. She never realized that God is a loving, merciful, and forgiving being, but she thinks she is all alone without even God's comfort. Nothing to look forward to, she thinks; she is so depressed she can't even cry. Weep for Jamie, indeed.

Actually, it probably has a million meanings. It's a lovely song; great chord progression.
