Have you ever been clinically depressed? (I don't mean that in any snarky way; you just don't reveal much about yourself so I have no idea what your issues really are or have been.) If you have, then you probably understand what utter hopelessness feels like and that it leaves a person unable to find reassurance within themselves. So having someone else like a therapist (could also be a friend or family member or someone else significant) remind you that all is not lost, that things will improve, that there are options out there, may be all that stands between you and completely giving up which can literally be deadly. While reassurance from other people may not be helpful to you for some reason, for most people that kind of reassurance and support enables them to keep hanging on through that hopelessness. It helps us survive.
