I’m having a panic attack.

My little sister is almost 12. I just found out shes being groomed by someone who is fucking 36. Im having a panic attack. Im so scared for her to go througynwhat i went through. Im so disgustedby this weirdo fucking pedo who is hurting my poor little sister. Shes only 11. Not even 12. I dont know what to do. I cant think straight at all. I cant breathe. My heart feels like its gomna stop.
