Ok. i dont have a kid with BP. but i AM bp.
cutting is certainly NOT the same as the dreaded "s".
Cutting for ME, is a release from the emotions that come up and want me to do the dreaded "s". So in a way its the physical pain crossing out the emotional pain. Its temporary and i try to NOT do it. The scars dont go away.

I know this is hard for you but you are doing so good by her. Try to not worry as much. Just keep telling her you love her. She needs to hear it as much as possible k? Aside from that,, be gentle with yourself. You are a wonderful mother!!!!
