Eva waken is used to these mood swings. Everyone else, not so much.
Eva has been struggling for the past four years ever since she was diagnosed with bipolar disorder.
the entire world never payed much attention to the bipolar disorder. being an illness that is fairly low on the attention list, people diagnosed with bipolar disorder mostly end up dying, either by killing themselves or by quietly killing their minds.
while Eva struggles between overjoyed thoughts and suicide thoughts, everyone else near her is just waiting for her next relapse. And this time, they don't have to wait much.
