Sometimes I think one of the most overvalued thing is someone else's judgement (or, more in general, society's judgement) about us, what we are, what we say, what we feel. Often it's a burden that stops us.
We also fear to admit we are weak and we can need help, not only because of the fear of judgement: sometimes it's a matter of pride, sometimes it's the will not to be of hindrance (especially for people we love), sometimes it's the fear to be in debt, or to lose (part of) our independence. There are so many shades, each person has its story, hence not everything works for everyone; but I think the common denominator to start a path to leave dangerous states of mind is in fact to admit we are in this trap, and to talk about it.
