Help in getting over emotional pain?

I was ually abused growing up, my very first memory is of something extremely horrible. Because of this during the earliest part of my schooling I was very inattentive. So my teachers told me I was slow and not smart enough for their cles. I was neglected at school by my teachers, they refused to teacher me because I was very spacey. As soon as I walked into cl I would be told to just go to the counselor and wait there. The counselor didn't pay attention to me either. Eventually I got older and began to occur, so I told someone. My father told me to say that it wasn't him but rather my grandpa that abused me. Since I was afraid of him I agreed, after all my grandpa molested me anyway. DHS got involved but I was too scared to get checked down there, I was 12. After that it happened off and on... Because the issue with ual abuse and education are linked I'm having problems dealing with criticism. And I hate myself, I feel guilty over everything. Therapy is planned also.
