Hi @Jojo 

I'm newly diagnosed too (about 2 months ago) - I have to say initially I was really not sure about it, couldn't quite work out what might be BPD and what was the bipolar that I already knew I had... but now I'm actually OK with it. 

I had to fill out a form to get into DBT group, where I had to write in against each diagnostic criteria how I matched that criteria now and in the past. I went from fighting against the diagnosis to actually convincing myself that I really probably did have it, and that finally getting the right treatment could only be a good thing. 

Hang in there, it gets less confronting with time.
