question: Hi my son Bradley left home 8 weeks ago.  His doctor said he was having a manic episode.  Since leaving he has made no attempt at contacting me.  I am unsure at this stage where he is now living.  I sometimes wonder whether he is borderline personality as well as Bipolar.  I am unsure whether he is taking his medication.  Do I wait this out as the doctor suggested and will he crash eventually.  He went to live with mt son who drinks heavily and maybe drugs involved.
