my best friend was a cutter for about a year that I know of, but one night she called me and said "I gave God my knife" and she was healed from the addiction. I prayed for her for so long it seemed like, and I have another friend who has been cutting for 7 years off and on, but I am praying that the Lord will take this from him as well and heal him. Please know I understand this is not the issue, there is some hurt that you have not healed from that Jesus can take from you if you'll just call on him and cry out to him continually to sanctify you and heal your hurt that is so deep... He did it for my friend, and he can really help you and lift your burden. Jesus bless you!
