I was talking to a Co-worker at work about Medication that I am on for Stress. I was telling him how I have Nightmares at night when I take medication of People Dieing and Killings going on in my Dreams. He goes to 2 other employees tells them that I am gonna come to work and Kill everyone. Wednesday of this past week I was brought into a meeting with 2 Bosses and 2 County Sheriff's who were accusing me of making a threat that I was gonna kill people at work. I have been put on Unpaid leave until I get an Evaluation by a Professional that my mind is not Physco.
