I’ve lost myself, but I want to find my way back. Any advice?

Hi everyone, Porn has destroyed me to the point where I barely recognize myself anymore. I’ve become lazy, unmotivated, and drained of energy. It feels like something inside me has shut down. And yet, in the middle of all this darkness, one small spark remains: the desire to change. I want to become someone better than who I am right now. But that spark alone isn’t enough. I can’t seem to find the strength to truly get back up. I keep falling into the same routine—doing nothing, wasting time, and putting everything off. School is falling apart too. I haven’t been going regularly for the past two months because I’ve lost all motivation and focus. Studying feels impossible. So I wanted to ask you: how do you keep going when it feels like there’s no strength left? Where do you find the will to fight when everything seems pointless? If you have any advice, even something small, I’d truly appreciate it.
