I lie a lot. So much that I can say I am a lie. I don’t want the pain of telling the truth. I’m lost in my lies. I really don’t know what to do .
Seek God’s forgiveness. Pray a lot, especially the Rosary. Ask the Holy Spirit to enter you and give you the strength to tell the truth.
Have you talked to your priest about it?
I think you should also seek psychiatric help with that. There must be an underlying reason for your compulsive lying. Only when you get to the true root of your problem can you begin to fully atone.
Pray, pray, pray! ask for the gift of self-restraint, that you do not say/answer so fast that a lie may slip out.
That you know you have a problem is the first step to healing. Seek the counsel of a priest and a good therapist.
