Am I A Bad Person

When I was younger, I lied about something serious. I was 11/12, and my lie only lasted about 24 hours until my friend figured it out. I'm way into my 20s now, and I still think about this every day. Sometimes I try to remember, and I think it didn't happen how I thought. That it was massively blown out of proportion rather than something I said as a kid for attention. But I also believe I have made myself to be a villain in my head and mis-remember it worse than it was. I think about it every day, it brings me so much turmoil in my head. I feel like im an awful person and I don't deserve to be here for the lie I told. It occasionally still gets talked about, not by me but by people around me, and I feel like everyone thinks I'm a horrible person even as an adult even though this happened more than 10 years ago. It makes me so miserable to think about that sometimes I feel suicidal when I do think about it. That I'm worthless and everyone around me deserves better. Am I a bad person? Do I deserve bad things to happen to me now because of this?
