I feel like I'm going to die, like my heart might stop at any moment, or that something catastrophically bad is imminent. I tried to call in sick but the call in line isn't working as if it's been disconnected so I emailed one of the supervisors and CC'd the rep to notify them of my absence tomorrow. But I feel threatened by something very bad like I'm going to drop dead. It's a state of paralyzing fear. It's been a very long time since it's been so bad.
