How to deal with an unpleasant English teacher?

Something is bothering me: I am going to take an English course (it's required for all the students that chose English as seconde language course)from a quite unfriendly teacher. I have had a course given by her last year, and that became almost a nightmare: 1. having missed a class of two(including one time that I have informed her beforehand), she came to me and said I didn't have to come again because that's the maximum number of class I might be missing. She got mad when I pointed out that on the regulation the number was 3 and said to me "anyway you won't pass..."

2. I was quite nervous one time when giving a presentation about something that I was that sure about, after that she came to me and said: wel, I don't konw if you are capable enough to follow this course, I have heard by the way your groupmates complaining about working with you, I think your English is really poor." That was really painful and mean, because I had very good contact with the group members, especially one girl (we were 4 people together) was always very kind to me. If they had any complaint, I believe they would tell me and try to give a hand, we work always together. But I was not so lost at that moment and forgot even asking why she is being that to a student? I suppose a teacher is someone you could always turn for help and rely on.

In the end I didnot pass the course of course, although I have tried. I was from then on being a kind doubt about myself, though I had very good marks from another English course which was even in a higher level.

Now I would probably again be picked up and told coldly: you are not good!

I want to stay cool this time and prove that I am good, but still I feel like that I need some encouragements. That's why I wrote this here.
