Hard drops after online play

Looking for advice as I’m not sure what to do. I keep falling into hard drops after my dom and I finish engaging in online play. I struggle with BPD as well and we both think it’s contributing to how quickly I fall into a bad drop but both of us aren’t sure how or where to proceed. He talks to me, I self soothe(cuddling my plushes, weighted blanket) but it still doesnt help. He’ll explain like the scientific reasonings behind it all, but it doesn’t really help me as I’m neurodivergent anyway. My dom is a switch himself but doesn’t drop really, which low-key makes me feel like I’m doing something wrong. anyway any advice either from someone who also has BPD struggles with online play or a combination of both will be really helpful or better aftercare ideas.
