Complain

These days I am crying every night.Because I am not satisfied with my master course, I am seriously crying. My eyes are swollen and my face changed.I worked for four years in Japan. During that time, I gave up many clothes and going out and eating and saved money.I might exaggerate things. Of course, I bought some clothes and sometime I went out with friends and enjoyed some things. But anyway, to come to UK and stay was expensive and not so easy for me. And now I am studying here.In my course, I need to learn some programming languages a bit. I do not have that kind of background. My course is basically for that kind of student. Usually, teachers just talk in front of the white board and we just listen. I think it is not a good way to learn programming. Learning that kind of thing requires a special environment where each student sits in front of a PC and able to ask immediately when they come across something strange, for at least one hour a week.I need to study on my own completely and when I come across something I don't understand I need to make an appointment with the teachers and visit them. When I visit,the teachers look busy and I can't ask more than one question and have to leave the rest.Students who are not satisfied with this course like me altogether require some laboratory classes where we can do some programming with teachers and teachers promised to us to have some classes one month ago.But still they do nothing about it and just leave it.
I feel completely abandoned and ignored.They just took my money which I saved for four years and do not give us enough support. I complained about it to the course director.I feel it is dangerous to complain too much because teachers are in a strong position above me. Now I've stopped crying and I'm studying on my own again.
I am a Master course student and supposed to study on my own to some
extent. But I can't understand, what the role of the teachers.
