Can’t stop thinking

Does anyone ever come across a particularly disturbing facebook post and can’t seem to get it out of their head?

I don’t usually have to deal with it sticking in my head but I forgot to take my medication the night before last and now I’m hyper-fixating on things. I keep seeing picture posts of animals with physical ailments from neglect and it genuinely makes me want to vomit and just freak out. I feel like I need to scrub down my entire body with a scrub and hot water or something or it’ll happen to me.
