TS, go to michael chong, consult him, then also make a polis report. After that if possible get some press coverage to disown him. However, if your parents refuse to disown him, then I say you are in deep shit. Lots of stuff he can still do to destroy your future.

Honestly, i thought parents like yours (esp your mom) existed only in tv dramas. Didn't know that they could go to such lengths for useless children like this
