My son is 19 it has become increasingly evident over the last 12 months that he is suffering.  While I am very wary of google diagnosis the fact sheet I found on this website  regarding BPD describes my sons behaviour exactly. We have tried over the last year to get him to seek help, knowing that something is wrong, he admits that something is wrong, we thought it was depression, he knew it wasn't he told me as much and we see now it is not.  We have had several harrowing weeks, seeing him become homeless, living in his car, losing yet another job, smashing phones, car,  ruining job prospects and many many heated relentless rants for the few days he was camped in our yard.  We got him home in the hope it would help, I tried to help him put his life back together.  I encouraged him to see a doctor.  He let me drive him to the hospital two days ago then refused to go in, I took him to a GP he got out of the car. He walked home packed up his things and left.

He messaged me from the carpark of a local shopping centre, we went to get him.  He physically assualted my husband, who tried to calm him down.  He ran.  We brought his car home knowing he would come back, hoping we could talk to him,  he turned up holding an axe handle with nails protruding from one end.  He said he wasn't going to hurt anyone,  it was for self defense.  We have never hurt him.  We called the police he ran.  Several times I contacted the emergency mental health line and headspace trying to find a way to help him.  He came back for his car the next morning.  I left the keys out with a letter containing contact details of Headspace, and this website.  I told him we loved him and want him home, but this time he has to meet us half way and begin treatment.  I sent him the info through facebook, he has since blocked me.

So sorry for going on, I am scared for him, seeing the information here gives me hope that there is help for him.  I don't know what to do.  I feel helpless, and dumb, for not seeing this all sooner.  The signes were there when he was younger, when I had an opportunity to take him for assessment and care, when he was too young to refuse.  I thought he would grow out of it, it was a phase, he would be okay.  The realisation now that he won't be, ever ok on his own is heartbreaking and hopeful at the same time.  

I have laid down an ultimatum any ideas on seeing it through, getting him to seek help?
