So I have this INFP friend, whom I've known for years and care about quite a bit. Lately, she's been saying things like "I give up on my future" and being very down on herself in general, saying she is stupid or a failure. My assertions that she is none of these things don't seem to help, and I feel as if my words sound insincere even though I mean them.
Any ideas for helping out a depressed INFP and boosting her confidence? Anyone who's been there, what would you want someone to say or do or ask?
