It's just too easy to blame the other person. I'm sure a lot of estrangements could be avoided if people simply swallowed their pride, apologised and kept their advice and opinions to themselves.
If they focused on how they could help (without expecting payback) and dropped the superior, 'I'm always right' mindset, they might avoid the pain of being shunned.
Having been brought up by a mother who really was mentally ill, it's irritating seeing labels casually thrown around.
The reality is that a child has nowhere to turn and doesn't even know what's normal. We blame ourselves and really believe that we must be very bad.
We automatically love our parents and fret endlessly about not being loved, even liked by them. Some of us are very lucky to have one good parent, though.
Mental health services (all health services), child protection, police, in fact our whole vital support system has been undermined by 'austerity' (a political move, never a necessity) and yet, although we all rely on them, directly or indirectly, for our support, safety, even our lives, many will vote for more of the same.
