I understand how you feel completely. Sometimes, you just can't take any more from people like that. Every job has one. Mine has a woman who has been with the company for 25+ years and who is a big bully. I tried to be nice to her, to ignore her, to understand her but she is the type of person who you have to stand up to or it gets worse. I'm from Flint, Michigan ( you all know what kind of reputation flint has) and was not about to let her continue to be so hateful to me!! The Flinttown part of me came out! Well, not all of it but the strong, determined side. I had to struggle to keep the part of it that wanted to beat her A** under control and I did.
It had gotten so bad with me and her that management sent us to employee counseling together. The counselor agreed with me and let mgmt have it for allowing this this woman to treat everyone so terrible. She didn't change but she certainly leaves me alone and most of her butt- kissing power with managment has been diminished. Good luck with your meeting.
