AITA for calling my friend a bully?

Is it mean to call someone a bully if you feel they actually bullied you? My friend did many things to me under the guise of friendship, but what takes the cake is her going through my room and spreading rumours about me because I take anxiety medication. She found it in my drawers. She told people I'm mentally unwell and tried to force her unwanted advice on mental health on me.

I ended the friendship because I felt bullied by her fo 2 years and we got into a confrontation where I said to her I think she can be a bully. She then started crying and is acting like I'm the bully. She says I'm a bad person. AITA for calling her a bully? Is it mean to call a bully a bully?
