I get panic attacks when I am around a certain person I know. What is this?

Whenever I am around someone I know I get major anxiety (or panic attacks) . I cry and I seek for cover, I don t want to make eye contact so I hide my face. I don t really even remember the reason, and I don t really want to either. I just want to cut her out of my life but I can t because my dad doesn t want me to and she constantly comes over. Is this ptsd? I think it started after she did something to me that made me cry. But it s not like I get flashbacks or anything, I just can not stand being around her. I just become panicked sad and angry all at once and when she leaves I feel emotionless for a period of time
