Recently my girlfriend and I have been arguing a lot. It's not that we are or need to break up, it's more that we are both dealing with a lot of stress and I've been experiencing a lot of depression.

This morning something that had to do with our dogs or something got us in to an argument. I have lost control of a lot of my temper and started raising my voice at her. It just turned in to a massive argument and I felt like I was going to get violent, so I went and took a bath and was extremely depressed so I just wouldn't talk to her. She wanted to talk about our relationship options and finally when I couldn't find any words because I was feeling so crappy, she was enraged also and said she was leaving me and started grabbing her stuff and her dog. She said she was going to call my mom and let her know how bad my depression is and so I went to go grab my keys to leave so that no one could find me. She just grabbed my wrist to stop me from leaving and I lost my s**t. I screamed for her not to touch me and started hysterically crying and screaming. She didn't know what to do but try to hold me so I wouldn't hurt her or hurt myself. I just kept screaming and hitting her trying to push her away. I crouched to the ground and covered my face and kept screaming and crying while she held me trying to calm me down. She said that it was so scary that she was on the verge of calling 911. And I couldn't stop. I couldn't calm down. It went on for a while. Then I would calm down and something small would upset me and the screaming/crying started again.

I can normally tell what my episodes are, but I have no idea what this is. And it's happened quite a bit throughout my past.

I am diagnosed Bipolar 1, BPD, ASPD, and I am 22 weeks pregnant.

Any ideas?
