Who else here has BPD, known as borderline personality disorder?

So I was diagnosed with bpd about a year ago maybe more. I’m just now getting into therapy and it’s been helpful so far. My question is what is helpful to others who have BPD? I’m just trying to find solution so I stop exploding and stop with the impulsive decisions. What do what do y’all do? What are ways that you get out of your head? What do you do about your favorite person situation? What do you do about the splitting?
