Omg, your coworker is the one that is dumb. With the help of a therapist I am learning that every single female, and I mean every single female, coworker that I worked with me was a back stabber. Right down to the coworkers that we Germans call Heucheler, right up to my so called boss, right up to the security people that were supposed to stop a criminal.
What I am learning now is totally frightening. After learning how jealousy drove these female coworkers to further abuse me is leaving me emotionally spent. What I am learning is so totally unbelievable, yet I am beginning to understand that all of the female coworkers I dealt with sided with the very criminal that stalked and harassed me repeatedly at work. Even females who worked there that I did not even know I am learning about now would stoop so low as to give me false information, false advice and let their own jealousy motivate them to hurt the one that was victimized.
People that I don't even know who had important evidence in a criminal case, all females, who rather hid this evidence and watched the victim suffer continiously in order to not only protect a criminal but in order to also protect their own behinds.
Who in actuality committed crimes themselves, who after blaming a victim for atrocious acts, then turned out to be the ones who themselves committed such atrocious acts.
Anyone that believes what a coworker says is only delivering his or her head on a platter. The American workplaces are a farce, filled with people who not only commit crimes but who will readily attempt to blame anyone for their failures.
You need to do what is right for you. Empower yourself, learn as much as you can about your own health. I have fared better health wise after doing a lot of medical research online. You can do that too.
It is a good thing I do not know your coworker, if you know what I mean.
