A small peice of my narrative draft

I'm obviously not proud of this, I've not been doing my best work recently. This is a small part of my narrative draft. I've not finished the full draft, so be expecting that in about a week. It's rather angsty, I'm not sorry. I know this has literally no context at all, but it will make sense soon (I hope) If you have any suggestions on how to change it please comment! I enjoy reading constructive criticism. It is just a draft so please don't be too harsh, lol.

Whenever I had to go out I was met with at least four people’s disappearance. Nobody seemed to notice the small raven-haired child screaming on the street. That discovery was hard on me, knowing I was ending people’s lives really took its toll. I was weak, physically and mentally. I was afraid to go out. My mind had aged thousands of years beyond what it was. I barely ate anymore, I hardly ever slept, I was depressed. At night my mind racing with thousands of horrific thoughts. It was poison, I poisoned myself continuously, I tried telling myself that it wasn't my fault. But the demons always won that fight My hair would stick up from tossing and turning all night. But for once, my bedraggled appearance was the least of my worries.
