Hello nomore80: Welcome to PC!

With regard to your concern, something is driving you to self-harm. Perhaps you know what it is. Or perhaps it is something that is buried within areas of your brain to which your conscious mind does not have access. If you're confident that your tendency to self-harm is now in the past, then there's no reason why you need to tell your doctor & therapist. It's really just up to you. On the other hand, if they aren't aware of this, they can't help you with it.

Of course, you could wait until you begin to feel yourself to be at risk again, or until you've actually done it again. But often, in that situation, people feel too embarrassed to share what's going on. So the whole scenario begins to take on a life of its own, so to speak. So, from my perspective, it's not a question of lying or not lying. It's a question of what is going to be most therapeutic. Personally, I would come down on the side of discussing what has occurred recently & how you're feeling now.
