Hello Budgie
I am very sorry to hear that things are so difficult for you right now, but it is great to see you reaching out for help and support - a very brave and scary thing to do!
This site is a support group for those who are or were in a relationship with a person with BPD, so many of the posts can be triggering to a BPD sufferer. There are resources of the type you're seeking. Please check out
Resources for BPD Sufferers.
Learning new skills through DBT can take time to master, small gentle steps work and I encourage you to continue your investment in DBT.
I wish you well on your journey.
