try alc if nothing else works
i’ve had dpdr for around 10 months and it feels so bad, its slowly getting better, VERY slowly, but the only thing that helps me is alcohol, not too much, but just a little to get you all calm like. if you are under 21 you can also drink kombucha and it helps alot too, im 185lbs and kombucha still has enough alc to get me more chill, and its legal, even for children. another thing i would recommend is getting really good at something, i got insanely good at fnf and it helps a bit to play or do something at such a high level to where you are focusing on trying really hard to win, hope this helps
