I really think therapy can still be useful even when you know/realize that this is a unnatural and artificial relationship. I know people disagree with this but it's obvious to me that therapists are mostly acting and pretending to care (whatever "care" means). It's fine with me, I just wish they were more honest about this for the sake of their clients. You can have a realistic approach towards therapists and therapy and still find it useful to talk about specific goals you want to reach/vent, etc.
