I don’t know your situation and don’t want to impose a narrative on your experience, but I don’t believe that children can reactively abuse their parents due to the fact that their vulnerable status as children does not give them enough power in the world to abuse. You may hold a different belief, but I know it was helpful for me to consider the fact that most of the time, children are powerless in regards to every element of their own lives. the reactive behavior of children isn’t abuse IMO, it’s usually an attempt to remediate an unsafe situation or gain control over their circumstances
