How long will this last?

I broke up with my abuser almost 2 months a go, but unfortunately I still live in a house with her and 4 other people. I've managed to escape for bits of this time by staying with friends or family, though I'm tied into this house and need to stay here so I can take my exams. I fucking hate it. I go through these intense feelings of guilt and shame, then I'll switch to being overcome by hate and rage. None of that shit's me, I've always been a really chirpy, non aggressive person, but this life is destroying me. Living with her is impossible. I'm so overcome with emotion I can't get out of bed, I'm going to fail all my exams, I can't eat, I have panic attacks daily and when I attempt to socialise I just have no words to say. Basically, the severity of my depression and anxiety symptoms have increased a lot since the breakup and I just have no hope for the future right now. We'll only live together for a couple more weeks, but what happens then? I'm not gonna be over this. I'll still be obsessing over her all the time, terrified she's going to be there or do something, it's just I won't have to make small talk with her when I'm cooking dinner. I can't do this. I can't keep doing this. I've lost so much of my life to her and I can't keep letting that happen. I don't know what to do.
