Hi @TrueColours and @sigillumdiaboli,
Welcome to the forums. I am a 39 year old woman with BPD, diagnosed when I was 19. I can see that if I'd been able to get into a DBT program all those years ago, I would be in a very different space by now. Alas, at that time DBT was only available through private hospitals which was beyond my mum's reach to pay for. I have however worked through the DBT treatment manual and skills training manual by myself and I do find the DBT skills helpful.
In my most recent search for a therapist (super long story!!!!), I was really frustrated by the fact that many therapists SAY they do DBT, but when you press them on it, it turns out they only do the skills component (which is only one of the three components of DBT). I think DBT is an excellent therapeutic approach to treating BPD...but to be truly effective, all three components (skills, individual therapy addressing underlying issues and between-session telephone support) need to be used. Thus I can definitely relate to your frustration about trying to find good support.
I hope you are able to find the support you are looking for @TrueColours and @sigillumdiaboli. I have to say, I find the forums super helpful in filling the void left by my current psychologist refusing to provide much between-session support (although happily, she has, after three months, softened her stance on this and is now a bit more available than she was).
