I've become fond of mixing BL with "The Presence Process", as they fill in gaps for each other, in my own view.
I have forgotten some particulars as it's been nearly a year since I worked with TPP, but it basically states that we will continue to replay old dramas until we face and drain the emotional energy from them. That would definitely support the idea of 'diving in' versus resist/persist.
The other point made in BL, if subtly, is that there is alot of this stuff to get through, so we do indeed have to be patient and tell ourselves that "this too shall, in fact, pass"... I admit I'm running mostly on faith and a what-have-I-got-to-lose mindset, but I forge ahead nonetheless...
