Why women are mean to me? I am a woman?

I noticed this thing lately, that the girls whom I considered as my friend or I thought we were in good terms, seem to be little mean to me. If something happens which will hurt my feelings, they bring attention to it deliberately and they have amused facial expressions. I get confused as I am always kind and supportive towards them it is very disheartening. I thought they were my friends. Even when I go to a new place women are mean to me without saying a word.

Their behavior is a reflection of them, people act unkindly due to their own perceived insecurities.
