The very first thing to do is to get a blood work-up. A very common cause of unexplained anger (especially in females) is a low hematocrit. This triggers a lizard-like response in the brain. It is noted by ER nurses who find a patient come in with blood loss cursing and obnoxious and become sweet as a lamb when they get on that IV and the transfusion kicks in. I suspect that the verbal aggressiveness has something to due with survival. When the immune system is depressed (or the body in danger from disease) the "aggressive person" response kicks in. This may not be the problem, but before going to psycho-therapy I would use Okam's razor and try the simplist explanation.
