I like this prayer from my 1983 Prayer Journal.
It has been very helpful for me.
Blessings and love, Fr. Jack.
A Healing Prayer
Only by calling on God are we able to forgive and forget.
Father, we praise you for your healing mercy.
Thank you for loving and accepting us
with all our hurts, hangups and sins,
but thank you even more
for caring enough to change us.
Thank you for saving us from ourselves
and our unwittingly self-destructive tendencies.
We reach out and open to receive your tender mercies,
praising you for showing us
that we are forgiven
so that we may be able to forgive -
both ourselves and others!
(Jon Eargle, Healing Where You Hurt on the Inside)
