Hello @Bianca3,
That's great you are looking for extra services as well as on a waiting list for a DBT program, have you looked at the Australian BPD Foundation website? There are some helpful online resources on there that you could read through:
Australian BPD Foundation
http://bpdfoundation.org.au/
I have also attached a online support and a module that you can work through in regards to distress intolerance:
Borderline Bravery is ran by a team of people with Borderline Personality Disorder from all across the globe. Their mission is to provide access to non-stigmatised resources and answers for other people with BPD.
A series of 4 online modules offered by The Centre for Clinical Interventions (WA Dept of Health).
Module 1: Understanding Distress Intolerance
Module 2: Accepting Distress
Module 3: Improving Distress
Module 4: Tolerating Distress
Take care of yourself,
Lunar 🙂
