I used to feel this way all the time when I was at work. Much worse even. I believed that co-workers were all against me, and trying to poison me.I was fired from that job.They said it was inadequate performance. But I know that was not the real reason. They believed I was mentally unfit for the job. I have a lawsuit against then now.As long as you don't act out aggressively like I did, then you should be ok. I always tell people, that nobody can hurt you unless they touch you.Words are just words and mean nothing to me at least. I hope you find a better way for dealing with the paranoia than I did.
