BPD is a disorder of emotional regulation and even tho it’s technically a personality disorder, I think it affects a lot of neurodivergent people as we usually have rejection sensitivity. It goes with bipolar often because it’s typified by explosive, unpredictable emotions, as well as unique communication style/needs, which is very autistic/adhd. It’s easy to find cool information on Instagram about BPD by BPD posters so i recommend reading more abt it :)
