Condition is inflicted via one already afflicted, via physical contact and channeling intense, magical energies into the victim.
Initial effects: Violent tendencies. Usually rage fueled, but other emotions mix in. Ones that are not thoughts that would have ever normally crossed my mind. An odd demand for companionship mixed in with attempts to murder my own companion. A highly unnatural thought process.
After-effects: Initial act of passion, one deemed as simply violence and not attempted murder, was followed by an intense headache and a nosebleed. My nose bred profusely for a while, and the headache was near crippling. All symptoms subsided after a time.
This will be deemed Stage One.
Third incident: She stabbed me, when I tried to attack her again. This time, I really did want to kill her. Such insane thoughts possessed me, of eternity. It's beginning to burn.
Forth incident: I tried to drain her. I felt so hungry. It was like every fiber of my being was yearning for it. All my energy was draining rapidly. I couldn't think. I'm losing control. It still burns. I can't think straight anymore.
