I'm so sorry you're going through this right now. I've been going through a crisis myself this week and I've called several crisis lines just to talk and cry more than once. I highly suggest calling one and speaking to them. I called both a generic crisis line and a DV one. They all listened with compassion and it helped calm me down in the moment.

ETA: I also went in person to a DV center and spoke with someone about creating a safety plan. That's a really good idea also. Stay safe.
