My counselor told me to burn mine. To have a celebration of sorts of how far I have come, and how my life is different now than in those journals. Freeing.
I will give you something funny to add. I don't know if this is an issue for everyone like it is for us, but we have a million socks in our house that never seem to have mates. Later in the evening, my children and I passed on the unmatched socks to the Sock Gods and burned all those too. We took pics and have a good laugh when it comes up.
I did both of these things in one day, and am glad we did something silly to lighten it up. FYI....kids were not home when I burned my journals!
