Some of us too eagerly embraced the darkness which made us into what we are. Others lost sight of who we were, as we Nobodies begin our tenuous pseudo-existences devoid of feelings...it becomes far too easy to follow our cruelest whims, lacking the ability to regret our actions. Still others became so desperate to reclaim what we had lost as to harm countless others in pursuit of that goal.

Only the first seems potentially a problem, in your circumstance. But darkness need not be a problem in and of itself, so long as you don't allow it to overwhelm you.
