Is it wrong for a teacher to bully his/her kids just because they have problems.?

Let me put it to you this way. I was raped when I was 6 years old. That left me with the mind of a 6 year old for some time. So, when I move to a new state, the middle school teachers see this problem, but instead of actually helping me or even offering help, they just decided to harass and bully me like a bunch of teenagers. Keep in mind that they were special ed teachers and right around 40-50 years old. They would, out of everybody, they'd pick on me to see if I was paying attention. Of course, with my current state, I was not able to fully pay attention. Other times, they would send me to detention for almost nothing, where the woman running the room would give me a piece of paper and ask me to write down what I did wrong and how I was going to improve. Many other times, they would yell at me and just be bullies. I told the vice principle about all of this, but he didn't believe me. I needed help and they didn't do anything. I, of course, had to help myself and get better after I moved away. So, I ask all of you. Was it wrong? They were those people who were obligated to help, but did nothing. If so, were they corruPT?
