Firstly, 15 years is incredible. I know that you are struggling again now and that's ok too, but that still needs to be acknowledged. I'm sorry to hear that you are going through all of this at the moment - I can't imagine how stressful it must be. Someone once explained to me the idea that self-injury is like any other addictions - in times of great stress if all your other coping mechanisms fail it can resurface.

Can you remember why you stopped at 15? What happened to bring about that change? Sometimes some of the techniques that helped then might be able to help you again now.
