this a free country and a free forum, so don't want to read, don't read

want to do something wrong, then don't be so cowardly as to force someone not to talk about it
You are not exactly fault free. Scanning and putting up everything about your family affairs for everyone to read is immature and unwise. You are cutting your own nose to spite your face.
In case, you haven't realise it, for someone reading the material you put up, the one and only inescapable conclusion (and I am sorry to have to say this) is that you are a spoilt brat.
A spoilt brat who complains about having to live in a HDB flat. A spoilt brat who complains about how "small" a HDB flat is. A spoilt brat with an unbridled sense of self-entitlement who stomps her feet, throws a tantrum and a fuss and threatens self-harm when she doesn't get her way or get to live in the outhouse of a large $20 million plus landed property. I can understand why it becomes impossible and unpleasant for your (step) mother to have to continue to live with you.
The issue is clearly about money. Let's face it, if you had received your "fair" share of $4 million or so instead of a "mere" $1 million, you would not be posting your family disputes in forums such as these as a form of blackmail.
Here's some advice for you. Admit that it is all about money. Admit that you have been behaving unreasonably. Visit your mum this Chinese New Year.
Sojo her, ask for forgiveness and make peace with your family. I am sure they will readily forgive you and welcome you back into the family just as I am sure that Mr Harold Chan, the deceased who you constantly take pains to emphasise is your father, will like to see that happen so that he can finally rest in peace.
