I was friends with people who had schizophrenia and bipolar but didn't tell me, they eventually got off their meds. because supposedly it's common for them to get off their meds because they feel normal and think the meds are necessary anymore.

It was a like being on a scary rollercoaster because they seem to make up stories and if you don't know they have mental issues you're trying to figure out what's wrong with them or trying to help them. Let's say I'm not friends with them anymore because it's difficult to have a friendship with them. Even their parents told me it's a constant rollercoaster. It's very sad for their parents to have to deal with that forever.
