Regardless of how it's caused, it's something within us; something that must be worked out the same way. That's what makes it hard. It's not an easy one to fix. We could be borderline between crazy and sane, though that wouldn't be anything clinical. Crazy enough to SI and have suicidal thoughts; constantly be thinking and brooding and putting ourselves down, constantly on the never-ending roller coaster, but sane enough that most of us can fake it most of the time. People don't necessarily know about it until we're close to the breaking point, and then they won't believe us because we've seemed so "normal" in their eyes all along. At least that's what I've experienced.
