my T had a similar conversation wiht me - i was calm and in control and talking about a plan i had - he went through it and by discussing it it did help me realise as FooZe said that i did actually want to live.
SO discussing these things is not always a bad thing if done in the right manner and yes my T uses DBT amoungst prob every other therapy known to man lol clever old T
