watching life fading away

we only have one life. one body and one soul. there is no second chance. every second of our lives can not come back. realizing that hurt me. from my soul. realizing that my youth, my most ‘precious’ years is wasted. if i make it to 40-50s, i will only remember i wasted these times. i know that, but i can’t do nothing. i have a broken soul, heart and mind. and i don’t know how to fix it, if it’s fixable
