Did I overreact?

I was molested as a child and my daughter was also sexually abused when she was 2. I'm extremely protective of her. She is 5 and also has ODD and has has trouble in school. She goes to the after school program and they have almost kicked her out because of her behavior. The same program has a summer program. My daughter still have behavior issues but has been doing better. But I found out it's because of a specific staff. A male staff ... In fact they send her to him when they can't get her behavior under control. That honestly made me so uncomfortable. I went to pick her up and saw this male staff and my daughter was holding on to the end of his shirt. I just went off and asked why my daughter is holding on to the end of his shirt. He said he doesn't like to do time outs. He does time ins. When the younger kids won't behave he has then hold onto the end of his shirt and follow him during the activity. I was just angry and accused him of grooming my daughter. I just kept yelling and I'll admit I was acting hysterical and kind of crazy. It got to the point where they threatened to call the cops on me and because of how I acted the coordinator of the childcare program called me and has suspended my child from the program. She said she understands ny concerns but how I acted was not ok. I now have nowhere for my daughter to go during work. I just want to keep her safe. The thought that she is only behaving better because of this male tells me he could have been touching her to get her to behave. Idk. I just don't want her help again
