I've namechanged.
When I was at secondary school, my (female) English teacher didn't like me at all and was very mentally abusive towards me. I was bullied at secondary school and didn't have many friends and the teacher picked up on this and basically joined in. She used to say she had never known a pupil as unpopular as me and it was obviously me that was to blame (I don't believe it was, I was/am a very quiet person and to be honest at school I wanted to learn). Not a lesson went by without her telling me, usually in front of the class, that I wasn't very nice, or with her basically joining in if others were being unkind to me. On the last lesson that she taught me for (at the end of year 11) she said again in front of the class that her biggest wish was that I would learn to grow up to be "human" and perhaps even - shock horror - make friends. What was horrible too was that she seemed to be everyone else's favourite teacher as she was "nice" to others except me. BTW I did have a few friends at school and since leaving school I've had no problems making friends.
It has now been almost 20 years since I left school. I have suffered with low self esteem for years mainly because of the bullying and her treatment contributed to that bullying I feel. She is still teaching at the same school, no doubt picking on other pupils. I've been having counselling for a couple of years and it's come to light that her comments have caused me so much harm mentally. I feel like I am making progress with my counselling now and I feel so angry towards her that I want to confront her. I've seen that she has a facebook profile which is open to receive messages and I feel like sending her a very assertive, but not aggressive, message saying how she has damaged me mentally and that she was a very mentally abusive teacher. Mainly with the intention of making her feel bad and making her think about her actions. It does concern me too that she is still teaching.
AIBU to send one or should I leave it?
