Sometimes I have really horrid intrusive thoughts that make me feel sick. I know rationally that they're things I'd never do and never reasonably even come close to considering, but sometimes if I'm in a particularly bad anxiety vortex I'll start tracing them onto hazy memories. They'll be things from years ago that I barely remember anyway, and then I'll start to panic and think that I have committed these awful deeds at some point even though the thought disgusts me. It's been happening more recently, and I keep worrying that I've hurt people I don't know anymore, or that I'm a monster because my memory is completely shot and all I've got to go on are these toxic thoughts that plague me now.

Is this something common for people with intrusive thoughts?
