Feeling Lost. I gone back to square one?

I don’t remember the last time I was happy.I am a prisoner of my own mind - home to my insecurities, fears and ghosts from the past. I’ve been sleeping too much these days. I wake up feeling drained and stale, trying to recover from a lengthy night of painful dreams, enough to make me shiver. I try to look for excuses to get out of bed, but I struggle to find those, too. I glance in the mirror and see an exhausted failure of a person. Someone who is slowly losing the will to live, but trying to hang on to something. Everything seems to be slipping from my fingers, like burning sand. I have given birth to several new scars, littered on my skin. It pains me to look at them and see what I’ve become – have I gone back to square one? I’ve been told that I’m strong and I can “get through” this. But “this,” this feeling of emptiness, of darkness and of a constant, painless pain – is nothing but a never-ending tunnel, and I’m struggling to find a way out.
