Dependency mode I wrote about stands on a stabile ground of conviction that whatever I do or say must be assessed by someone else. It's only some other people who can give us the right to undertake certain actions, and, what is worse, to live in general. We seldom ask the question who gave this right to them and rarely asked us why we gave it away. But these are the fundamental issues of ours. 
It is a matter of mindset - we are led by some thoughts that impact our bodies, emotions, and decision processes, yet we are not aware of them. These very thoughts had been imprinted a long time ago by significant people, authorities at that time, and there is no surprise that in their interest was to make of us obedient puppets. In plain words, we were taught what to think, not how to think. 
Dependency mode causes we are afraid of being judged and condemned. The more we are scared, the bigger the risk of becoming a developed narc or a suicide (the latter, more likely), for we do not belong to ourselves. Never! And for many of us, there comes the day when there is this one wrong assessment too much of handling.
