Marriage Annulment - After being married for 3 months a certain behavi

I recently got married and had told my now husband I had been treated for Anxiety Disorder. Just before the marriage i saw a behavior in my husband that i cannot live with. He got extremely angry which was scary...I talked to him about it and he said it was stress and that will I not be happy if people said I changed him. After we got in the marriage I saw the same behavior of Violence and it has even led to me getiing a beating - domestic Violence. Now my condition has moved from Anxiety Disorder to Major Depression Disorder. I cannot live the rest of my life with a person who behaves like this. I then asked a couple of his family members and it have confirmed that this is a behaviour he grew up with. What do i do. It looks like they concealed a behaviour that I should have made an informed decision before entering into the marriage about.
