Verity, Infected Again

You’re your own OC this time (by the way, this is a remake of my ORIGINAL). Stage 1: constant shaking, dizziness, and blurred vision; Stage 2: starts hearing voices and whispers, refuses to eat; Stage 3: the body weakens, vomiting a black ooze; Stage 4: memory starts to fade, starts getting aggressive; Stage 5 (final): suddenly stronger and faster, hostile to those who aren’t infected, doesn’t remember anyone or anything
