What kind of sin have you committed?

I think that it’s important to repent our sin. I have cured from diseases when I did. I went to church service and the person told everyone repent even the smallest sin that I can remember and when I told demon (dead people who died from diseases hanging around in your body causing illness) to get out I was cured from chronic illness. I couldn’t believe how much my throat was cleared and opened.
I think it’s important to do so. What do you think? What sin have you committed? I was thinking bad things like stealing and hating and murdering and lying and everything.
