I am an INFP and I can sense the INFPness in an actor, I guess. Hmmm, I don't know Michelle as an actress, so I can't say she's an INFP. Johnny Depp could be an INFP. INFPs are serious but also seriously funny.
But reading the posts, there is a chance Michelle can be an INFP. I can be dark & self-destructive too when I think I've had too much (emotions & frustrations). I smoke too. Being oversensitive is just so d*** tiring.
