Overwhelming Doubt

Can I do it? Do I have it within me? My doubts are telling me I cannot definitively But more than that, I feel it too A feeling of sickness, what more can I do? I must gain control, or I'll forever be controlled I must change this, so my story can unfold But the doubt is overwhelming, it shackles me And while I know the key lies within my mind, simply knowing does not set me free It's like asking a dying man to accept a new reality, despite living without it through the years He may know he must accept it, perhaps he has always known, but time and practice would be the best way to defeat his fears
