Lost on what to do

I made a mistake to a friend without meaning to hurt her, our mutual friend talked to me about how mad she is at me and she took my insecurities I shared with her and threw at my face saying how the acting is getting old. I'm really lost because I apologized and never meant to hurt anyone but she just says how I'm just trying to keep an image and to get rid of me feeling guilty. I don't know what to do
