Ocd made me vegetarian and avoid eating at people houses

Context: I'm mexican which means lots of parties

I became vegetarian because I was convinced all the meat and chicken we were buying was human meat. Then I couldn't eat beans from other people's houses because I was convinced they shit in them as they have a grudge against me and my family. I was convinced their rice had maggots.

It made it hard for me to enjoy food at people's parties. And yesterday we went to a party where they put meat in the beans and I freaked out .
