Dealing with Borderline Personality Disorder on top of Dissociative Identity Disorder

I'm both lucky and unlucky I suppose. I have two disorders which completely suck, but they interact very well with each other and actually seem to keep each other in check.

My Dissociative Identity Disorder (DID) keeps my Borderline Personality Disorder (BPD) symptoms compartmentalized into easier to deal with outbursts. To a point where I'm scared that I'll 'grow out of' my BPD and be lost as how to deal with my DID. I don't know. I'm probably just rambling at this point. I need sleep for work tomorrow.
