I'm sorry to hear that - and I hope you're doing fine now. I really didn't have any "bad" experience like that (mania is awesome fun ;)), of course, the downside was depression followed by years of medication. They make such a deal about it being a "bad idea to leave midway through" ... I'm glad your teacher said you should (although even then, they're really ejecting you in what must be a pretty vulnerable situation). Anyway, hope you're doing fine now.
That's what I was hoping for! just kidding. But no, for the most part I think I'm totally fine and I don't think vipassana caused anything new, I've always had intrusive thoughts and trouble focusing, but in general I'm fairly successful and lead a pretty normal life. Who knows what would have happened had I stayed, it's quite possible that things would have been much worse. I know I felt emotionally drained for a few weeks afterwards and almost numb.
