My boyfriend and I got into an argument, and long story short, he ended up saying something along the lines of “at least I’m not a depressed bitch, waaah look at me, I have depression”, and I ended up hitting him in the face.
From that, he immediately got up and whacked me with a chair a couple of times. I couldn’t believe what I had done and I immediately said I was a monster and that he should just leave me. He refused, and even comforted my undeserving, crying, pathetic ass. I even told him to punch me in the face right back for it, which he did. He totally forgave me and said to not even worry about it, but I can’t forgive myself. What should I do? (Give me your honest answer, and don’t mention what he did because it isn’t the problem here.)

You two need counseling asap. You most of all. That’s a seriously abusive relationship. Things should never come to violence and making fun of someone who is depressed is messed up. I would definately take some time off from this relationship if it were me so I could go get help.
Let me explain it to you this way: I wear glasses to see. Without these glasses I can’t see anything, but shapes. Now if my glasses were to break, I would get new glasses, because I NEED THE GLASSES TO SEE. Why would you ignore your depression instead of getting help? It’s just like a broken leg or needing glasses and there is no shame in it. Would you stay with the boyfriend if he was making fun of your broken leg? OH HELL TO THE NO! He needs to understand that this is a serious issue and you do too. If he won’t go with you then you need to move on, because this isn’t a good way to live your life and continueing in this direction means there won’t be a life to live much longer.
I suffer from mental illness and is not a laughing matter. I’m on a steady diet of prescriptions and would never be in a relationship where I suffered mental or physical abuse. I love myself to much to allow that to happen. Ultimately the decision is up to you. However in my opinion there is never a reason to resort to violence in a relationship. Regardless of who used it. Happens once, will eventually happen again.
