Found out my brother is a pedophile

Can’t stomach anything to eat. I went for a walk but got scared. Everything around me looks like a video game and I haven’t closed my mouth yet. He [M 29] has three little kids all under 9 years old and he was texting our 14 year old cousin for the past 7 months. He told her it’s not wrong. I think I’m seeing actually red it’s like everything around me is so loud I can hardly look at anything for more than a moment my head is just on a swivel I’m going completely nuts
