I've done some things in my past which I'd prefer not to say that I feel tremendously guilty for. I don't do these things anymore and I'm attempting to turn my life around. But because of the guilt, I feel like I don't deserve to put my past behind me. Can I get some advice?
One of the hardest things about turning over new leaves is our own inability to forgive ourselves.
Whatever you did is done. If you can, make reparation and move on. If you cannot repair any damage done then make the rest of your life count for something, but the first step is to give yourself a break.
We all make mistakes in life, learn from them and move on.
