partner uses diagnosis against me

Hi,
This is my first post on this site. I don't know where else I can talk about this. I have BPD, and whenever my partner and I get into an argument, she uses it against me. I admit that my emotions have sometimes gotten overwhelming and out of control during arguments. But she pulls the BPD card even when I'm calmly telling her that I'm hurt. For example, I'll tell her that something she said hurt me, and she'll say something like "you've got BPD so bad and you can't even see it" or "you're just having a BPD episode." She'll also tell me multiple times to take a sedative pill that I've been prescribed. Again, this happens when my emotions are NOT overwhelming. I've been going to DBT for several months, and gotten to a good place with my medication, and I'm starting to be able to stay in my "wise mind" for longer before I reach my limit and have to take a break from the conversation. It's so incredibly hurtful when she uses my diagnosis against me like that. It makes me feel like she sees me as a disorder and not a person, and that she doesn't care about how I feel. When she tells me to take my medication, it feels like she just wants me to shut up. I feel like I'm being emotionally abused and controlled. I hate that she does it and I want so badly for her to stop. Please, I really need to hear some outside perspectives on this.
