It depends whether I have to deal with them or not. I had to deal with a very mean group of women once. It gave me IBS. Also, what is their reason for being mean to you? In the case of these women, they were up to no good and I was new in charge to stop them. Silly me for taking that on.

Yes, if you can avoid them, just do. It's no reflection on your value because they are mean to you. It's a reflection of theirs.
