It may be that somebody depressed does not feeling like exploring unknowns, or brave enough to lose himself and experience something completely different. Also, I don't think it's necessary wise to suggest somebody depressed go on such trip. It can take you different places. Sure, it may be fine 9 out of 10 times, but if somebody gets stuck in some negative positive feedback loop (heh) he may end up with a trauma.
