I think that makes total sense. It comes down to the feeling of control and the fight or flight instinct. Depression, anxiety, or whatever problem is overwhelming you currently is extremely exhausting to deal with. If fighting your way out of your problems doesn't seem to work, you just decide to run away, but no matter how far you run away, the problems will at one point catch up to you. Now you feel trapped and totally out of control, which just makes the problems feel way worse... that is, until you see CTB as a viable option to deal with your problems. Finally, you have a way out, and you feel in control again, which can be a huge boost for your mental health. You have some kind of hope again that things might be okay someday.
